|
||
<p><code>ResourceDef</code>s are effectively a way to transform the a custom resource pattern syntax into
|
||
suitable regular expressions from which to check matches with paths and capture portions of a
|
||
matched path into variables. Common cases are on a fast path that avoids going through the
|
||
regex engine.</p>
|
||
<h2 id="pattern-format-and-matching-behavior"><a class="doc-anchor" href="#pattern-format-and-matching-behavior">§</a>Pattern Format and Matching Behavior</h2>
|
||
<p>Resource pattern is defined as a string of zero or more <em>segments</em> where each segment is
|
||
preceded by a slash <code>/</code>.</p>
|
||
<p>This means that pattern string <strong>must</strong> either be empty or begin with a slash (<code>/</code>). This also
|
||
implies that a trailing slash in pattern defines an empty segment. For example, the pattern
|
||
<code>"/user/"</code> has two segments: <code>["user", ""]</code></p>
|
||
<p>A key point to understand is that <code>ResourceDef</code> matches segments, not strings. Segments are
|
||
matched individually. For example, the pattern <code>/user/</code> is not considered a prefix for the path
|
||
<code>/user/123/456</code>, because the second segment doesn’t match: <code>["user", ""]</code>
|
||
vs <code>["user", "123", "456"]</code>.</p>
|
||
<p>This definition is consistent with the definition of absolute URL path in
|
||
<a href="https://datatracker.ietf.org/doc/html/rfc3986#section-3.3">RFC 3986 §3.3</a></p>
|
||
<h2 id="static-resources"><a class="doc-anchor" href="#static-resources">§</a>Static Resources</h2>
|
||
<p>A static resource is the most basic type of definition. Pass a pattern to <a href="struct.ResourceDef.html#method.new" title="associated function actix_web::dev::ResourceDef::new">new</a>.
|
||
Conforming paths must match the pattern exactly.</p>

<h2 id="dynamic-segments"><a class="doc-anchor" href="#dynamic-segments">§</a>Dynamic Segments</h2>
|
||
<p>Also known as “path parameters”. Resources can define sections of a pattern that be extracted
|
||
from a conforming path, if it conforms to (one of) the resource pattern(s).</p>
|
||
<p>The marker for a dynamic segment is curly braces wrapping an identifier. For example,
|
||
<code>/user/{id}</code> would match paths like <code>/user/123</code> or <code>/user/james</code> and be able to extract the user
|
||
IDs “123” and “james”, respectively.</p>
|
||
<p>However, this resource pattern (<code>/user/{id}</code>) would, not cover <code>/user/123/stars</code> (unless
|
||
constructed as a prefix; see next section) since the default pattern for segments matches all
|
||
characters until it finds a <code>/</code> character (or the end of the path). Custom segment patterns are
|
||
covered further down.</p>
|
||
<p>Dynamic segments do not need to be delimited by <code>/</code> characters, they can be defined within a
|
||
path segment. For example, <code>/rust-is-{opinion}</code> can match the paths <code>/rust-is-cool</code> and
|
||
<code>/rust-is-hard</code>.</p>
|
||
<p>For information on capturing segment values from paths or other custom resource types,
|
||
see <a href="struct.ResourceDef.html#method.capture_match_info" title="method actix_web::dev::ResourceDef::capture_match_info"><code>capture_match_info</code></a>
|
||
and <a href="struct.ResourceDef.html#method.capture_match_info_fn" title="method actix_web::dev::ResourceDef::capture_match_info_fn"><code>capture_match_info_fn</code></a>.</p>
|
||
<p>A resource definition can contain at most 16 dynamic segments.</p>

<p>A prefix resource is defined as pattern that can match just the start of a path, up to a

|
||
<p>Prefix patterns with a trailing slash may have an unexpected, though correct, behavior.

this behavior after reading the <a href="#pattern-format-and-matching-behavior">matching behavior section</a>. Examples are given below.</p>

<h2 id="custom-regex-segments"><a class="doc-anchor" href="#custom-regex-segments">§</a>Custom Regex Segments</h2>
|
||
<p>Dynamic segments can be customised to only match a specific regular expression. It can be
|
||
helpful to do this if resource definitions would otherwise conflict and cause one to
|
||
be inaccessible.</p>
|
||
<p>The regex used when capturing segment values can be specified explicitly using this syntax:
|
||
<code>{name:regex}</code>. For example, <code>/user/{id:\d+}</code> will only match paths where the user ID
|
||
is numeric.</p>
|
||
<p>The regex could potentially match multiple segments. If this is not wanted, then care must be
|
||
taken to avoid matching a slash <code>/</code>. It is guaranteed, however, that the match ends at a
|
||
segment boundary; the pattern <code>r"(/|$)</code> is always appended to the regex.</p>
|
||
<p>By default, dynamic segments use this regex: <code>[^/]+</code>. This shows why it is the case, as shown in
|
||
the earlier section, that segments capture a slice of the path up to the next <code>/</code> character.</p>
|
||
<p>Custom regex segments can be used in static and prefix resource definition variants.</p>

|
||
<p>As a shortcut to defining a custom regex for matching <em>all</em> remaining characters (not just those
|
||
up until a <code>/</code> character), there is a special pattern to match (and capture) the remaining
|
||
path portion.</p>
|
||
<p>To do this, use the segment pattern: <code>{name}*</code>. Since a tail segment also has a name, values are
|
||
extracted in the same way as non-tail dynamic segments.</p>

|

<p>For resources that can map to multiple distinct paths, it may be suitable to use
|
||
multi-pattern resources by passing an array/vec to <a href="struct.ResourceDef.html#method.new" title="associated function actix_web::dev::ResourceDef::new"><code>new</code></a>. They will be combined
|
||
into a regex set which is usually quicker to check matches on than checking each
|
||
pattern individually.</p>
|
||
<p>Multi-pattern resources can contain dynamic segments just like single pattern ones.
|
||
However, take care to use consistent and semantically-equivalent segment names; it could affect
|
||
expectations in the router using these definitions and cause runtime panics.</p>

|

<p>It should be noted that this library takes no steps to normalize intra-path or trailing slashes.

As such, all resource definitions implicitly expect a pre-processing step to normalize paths if

you wish to accommodate “recoverable” path errors. Below are several examples of resource-path

pairs that would not be compatible.</p>

<p>The check function is given a reference to the passed resource and optional arbitrary data.

This is useful if you want to conditionally match on some non-path related aspect of the

resource type.</p>
