API documentation for the Rust `Timeout` struct in crate `actix_web`.
Keywords: rust, rustlang, rust-lang, Timeout

# [−] Struct actix_web::actix::fut::Timeout

    #[must_use = "futures do nothing unless polled"]
    pub struct Timeout<F> where
        F: ActorFuture,  { /* fields omitted */ }

Future for the `timeout` combinator, interrupts computations if it takes more than `timeout`.

This is created by the `ActorFuture::timeout()` method.

## 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`)
