std::marker::Send - Rust
Description: API documentation for the Rust `Send` trait in crate `std`.
Keywords: rust, rustlang, rust-lang, Send

# Trait std::marker::Send 1.0.0[−][src]

    pub unsafe auto trait Send { }

Types that can be transferred across thread boundaries.

This trait is automatically implemented when the compiler determines it's appropriate.

An example of a non-`Send` type is the reference-counting pointer `rc::Rc`. If two threads attempt to clone `Rc`s that point to the same reference-counted value, they might try to update the reference count at the same time, which is undefined behavior because `Rc` doesn't use atomic operations. Its cousin `sync::Arc` does use atomic operations (incurring some overhead) and thus is `Send`.

See the Nomicon for more details.

## 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`)
