# [−][src]Struct actix_web::http::Cookie

    pub struct Cookie<'c> { /* fields omitted */ }

Representation of an HTTP cookie.

# Constructing a `Cookie`

To construct a cookie with only a name/value, use the new method:

    use cookie::Cookie;

    let cookie = Cookie::new("name", "value");
    assert_eq!(&cookie.to_string(), "name=value");

To construct more elaborate cookies, use the build method and `CookieBuilder` methods:

    use cookie::Cookie;

    let cookie = Cookie::build("name", "value")
        .domain("www.rust-lang.org")
        .path("/")
        .secure(true)
        .http_only(true)
        .finish();

## Methods

###

`impl Cookie<'static>`

[src]

####

`pub fn new<N, V>(name: N, value: V) -> Cookie<'static> where N: Into<Cow<'static, str>>, V: Into<Cow<'static, str>>,`

[src]

Creates a new `Cookie` with the given name and value.

# Example

    use cookie::Cookie;

    let cookie = Cookie::new("name", "value");
    assert_eq!(cookie.name_value(), ("name", "value"));

####

`pub fn named<N>(name: N) -> Cookie<'static> where N: Into<Cow<'static, str>>,`

[src]

Creates a new `Cookie` with the given name and an empty value.

# Example

    use cookie::Cookie;

    let cookie = Cookie::named("name");
    assert_eq!(cookie.name(), "name");
    assert!(cookie.value().is_empty());

####

`pub fn build<N, V>(name: N, value: V) -> CookieBuilder where N: Into<Cow<'static, str>>, V: Into<Cow<'static, str>>,`

[src]

Creates a new `CookieBuilder` instance from the given key and value strings.

# Example

    use cookie::Cookie;

    let c = Cookie::build("foo", "bar").finish();
    assert_eq!(c.name_value(), ("foo", "bar"));

###

`impl<'c> Cookie<'c>`

[src]

####

`pub fn parse<S>(s: S) -> Result<Cookie<'c>, ParseError> where S: Into<Cow<'c, str>>,`

[src]

Parses a `Cookie` from the given HTTP cookie header value string. Does not perform any percent-decoding.

# Example

    use cookie::Cookie;

    let c = Cookie::parse("foo=bar%20baz; HttpOnly").unwrap();
    assert_eq!(c.name_value(), ("foo", "bar%20baz"));
    assert_eq!(c.http_only(), Some(true));

####

`pub fn parse_encoded<S>(s: S) -> Result<Cookie<'c>, ParseError> where S: Into<Cow<'c, str>>,`

[src]

Parses a `Cookie` from the given HTTP cookie header value string where the name and value fields are percent-encoded. Percent-decodes the name/value fields.

This API requires the `percent-encode` feature to be enabled on this crate.

# Example

    use cookie::Cookie;

    let c = Cookie::parse_encoded("foo=bar%20baz; HttpOnly").unwrap();
    assert_eq!(c.name_value(), ("foo", "bar baz"));
    assert_eq!(c.http_only(), Some(true));

####

`pub fn encoded(&'a self) -> EncodedCookie<'a, 'c>`

[src]

Wraps `self` in an `EncodedCookie`: a cost-free wrapper around `Cookie` whose `Display` implementation percent-encodes the name and value of the wrapped `Cookie`.

This method is only available when the `percent-encode` feature is enabled.

# Example

    use cookie::Cookie;

    let mut c = Cookie::new("my name", "this; value?");
    assert_eq!(&c.encoded().to_string(), "my%20name=this%3B%20value%3F");

####

`pub fn into_owned(self) -> Cookie<'static>`

[src]

Converts `self` into a `Cookie` with a static lifetime. This method results in at most one allocation.

# Example

    use cookie::Cookie;

    let c = Cookie::new("a", "b");
    let owned_cookie = c.into_owned();
    assert_eq!(owned_cookie.name_value(), ("a", "b"));

####

`pub fn name(&self) -> &str`

[src]

Returns the name of `self`.

# Example

    let c = Cookie::new("name", "value");
    assert_eq!(c.name(), "name");

####

`pub fn value(&self) -> &str`

[src]

Returns the value of `self`.

# Example

    use cookie::Cookie;

    let c = Cookie::new("name", "value");
    assert_eq!(c.value(), "value");

####

`pub fn name_value(&self) -> (&str, &str)`

[src]

Returns the name and value of `self` as a tuple of `(name, value)`.

# Example

    use cookie::Cookie;

    let c = Cookie::new("name", "value");
    assert_eq!(c.name_value(), ("name", "value"));

####

`pub fn http_only(&self) -> Option<bool>`

[src]

Returns whether this cookie was marked `HttpOnly` or not. Returns `Some(true)` when the cookie was explicitly set (manually or parsed) as `HttpOnly`, `Some(false)` when `http_only` was manually set to `false`, and `None` otherwise.

# Example

    use cookie::Cookie;

    let c = Cookie::parse("name=value; httponly").unwrap();
    assert_eq!(c.http_only(), Some(true));

    let mut c = Cookie::new("name", "value");
    assert_eq!(c.http_only(), None);

    let mut c = Cookie::new("name", "value");
    assert_eq!(c.http_only(), None);

    // An explicitly set "false" value.
    c.set_http_only(false);
    assert_eq!(c.http_only(), Some(false));

    // An explicitly set "true" value.
    c.set_http_only(true);
    assert_eq!(c.http_only(), Some(true));

####

`pub fn secure(&self) -> Option<bool>`

[src]

Returns whether this cookie was marked `Secure` or not. Returns `Some(true)` when the cookie was explicitly set (manually or parsed) as `Secure`, `Some(false)` when `secure` was manually set to `false`, and `None` otherwise.

# Example

    use cookie::Cookie;

    let c = Cookie::parse("name=value; Secure").unwrap();
    assert_eq!(c.secure(), Some(true));

    let mut c = Cookie::parse("name=value").unwrap();
    assert_eq!(c.secure(), None);

    let mut c = Cookie::new("name", "value");
    assert_eq!(c.secure(), None);

    // An explicitly set "false" value.
    c.set_secure(false);
    assert_eq!(c.secure(), Some(false));

    // An explicitly set "true" value.
    c.set_secure(true);
    assert_eq!(c.secure(), Some(true));

####

`pub fn same_site(&self) -> Option<SameSite>`

[src]

####

`pub fn name_raw(&self) -> Option<&'c str>`

[src]

Returns the name of `self` as a string slice of the raw string `self` was originally parsed from. If `self` was not originally parsed from a raw string, returns `None`.

This method differs from name in that it returns a string with the same lifetime as the originally parsed string. This lifetime may outlive `self`. If a longer lifetime is not required, or you're unsure if you need a longer lifetime, use name.

# Example

    use cookie::Cookie;

    let cookie_string = format!("{}={}", "foo", "bar");

    // `c` will be dropped at the end of the scope, but `name` will live on
    let name = {
        let c = Cookie::parse(cookie_string.as_str()).unwrap();
        c.name_raw()
    };

    assert_eq!(name, Some("foo"));

####

`pub fn value_raw(&self) -> Option<&'c str>`

[src]

Returns the value of `self` as a string slice of the raw string `self` was originally parsed from. If `self` was not originally parsed from a raw string, returns `None`.

This method differs from value in that it returns a string with the same lifetime as the originally parsed string. This lifetime may outlive `self`. If a longer lifetime is not required, or you're unsure if you need a longer lifetime, use value.

# Example

    use cookie::Cookie;

    let cookie_string = format!("{}={}", "foo", "bar");

    // `c` will be dropped at the end of the scope, but `value` will live on
    let value = {
        let c = Cookie::parse(cookie_string.as_str()).unwrap();
        c.value_raw()
    };

    assert_eq!(value, Some("bar"));

####

`pub fn path_raw(&self) -> Option<&'c str>`

[src]

Returns the `Path` of `self` as a string slice of the raw string `self` was originally parsed from. If `self` was not originally parsed from a raw string, or if `self` doesn't contain a `Path`, or if the `Path` has changed since parsing, returns `None`.

This method differs from path in that it returns a string with the same lifetime as the originally parsed string. This lifetime may outlive `self`. If a longer lifetime is not required, or you're unsure if you need a longer lifetime, use path.

# Example

    use cookie::Cookie;

    let cookie_string = format!("{}={}; Path=/", "foo", "bar");

    // `c` will be dropped at the end of the scope, but `path` will live on
    let path = {
        let c = Cookie::parse(cookie_string.as_str()).unwrap();
        c.path_raw()
    };

    assert_eq!(path, Some("/"));

####

`pub fn domain_raw(&self) -> Option<&'c str>`

[src]

Returns the `Domain` of `self` as a string slice of the raw string `self` was originally parsed from. If `self` was not originally parsed from a raw string, or if `self` doesn't contain a `Domain`, or if the `Domain` has changed since parsing, returns `None`.

This method differs from domain in that it returns a string with the same lifetime as the originally parsed string. This lifetime may outlive `self` struct. If a longer lifetime is not required, or you're unsure if you need a longer lifetime, use domain.

# Example

    use cookie::Cookie;

    let cookie_string = format!("{}={}; Domain=crates.io", "foo", "bar");

    //`c` will be dropped at the end of the scope, but `domain` will live on
    let domain = {
        let c = Cookie::parse(cookie_string.as_str()).unwrap();
        c.domain_raw()
    };

    assert_eq!(domain, Some("crates.io"));

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
