std::future::Ready - Rust
Description: API documentation for the Rust `Ready` struct in crate `std`.
Keywords: rust, rustlang, rust-lang, Ready

# [−][src]Struct std::future::Ready

    #[must_use = "futures do nothing unless you `.await` or poll them"]pub struct Ready<T>(_);

🔬 This is a nightly-only experimental API. (`future_readiness_fns` #70921)

Creates a future that is immediately ready with a value.

This `struct` is created by the `ready` function. See its documentation for more.
