# Module std::raw [−] [src]

Unstable (`raw` #27751)

Contains struct definitions for the layout of compiler built-in types.

They can be used as targets of transmutes in unsafe code for manipulating the raw representations directly.

Their definition should always match the ABI defined in `rustc::back::abi`.

## Structs

Slice | [Deprecated] [Unstable] The representation of a slice like `&[T]`.
TraitObject | [Unstable] The representation of a trait object like `&SomeTrait`.

## Traits

Repr | [Deprecated] [Unstable] This trait is meant to map equivalences between raw structs and their corresponding rust values.

## 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`)
