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

# Trait std::ops::ShlAssign 1.8.0 [−] [src]

    #[lang = "shl_assign"]
    pub trait ShlAssign<Rhs> {
        fn shl_assign(&mut self, rhs: Rhs);
    }

The left shift assignment operator `<<=`.

# Examples

A trivial implementation of `ShlAssign`. When `Foo <<= Foo` happens, it ends up calling `shl_assign`, and therefore, `main` prints `Shifting left!`.

    use std::ops::ShlAssign;

    struct Foo;

    impl ShlAssign<Foo> for Foo {
        fn shl_assign(&mut self, _rhs: Foo) {
            println!("Shifting left!");
        }
    }

    fn main() {
        let mut foo = Foo;
        foo <<= Foo;
    }Run

## Required Methods

### `fn shl_assign(&mut self, rhs: Rhs)`

The method for the `<<=` operator

## 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`)
