core::intrinsics::volatile_set_memory - Rust
Description: API documentation for the Rust `volatile_set_memory` fn in crate `core`.
Keywords: rust, rustlang, rust-lang, volatile_set_memory

# Function core::intrinsics::volatile_set_memory [−] [src]

    pub unsafe extern "rust-intrinsic" fn volatile_set_memory<T>(dst: *mut T,
                                                                 val: u8,
                                                                 count: usize)

Unstable (`core_intrinsics`)

: intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

Equivalent to the appropriate `llvm.memset.p0i8.*` intrinsic, with a size of `count` * `size_of::<T>()` and an alignment of `min_align_of::<T>()`.

The volatile parameter is set to `true`, so it will not be optimized out.

## 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`)
