Expand description

A type which knows what its layout is.

This does not refer to layout in Rust.

Required Methods§

source

fn layout(&self) -> &Layout

Returns the layout for objects of this type.

Provided Methods§

source

fn size(&self) -> usize

Returns the size, in bytes, for objects of this type.

Intentionally returns usize rather than Size, so callers will have to explicitly convert with row_size_for_bytes.

source

fn align(&self) -> usize

Returns the alignment, in bytes, for objects of this type.

Intentionally returns usize rather than Size, so callers will have to explicitly convert with row_size_for_bytes.
