Struct alloc_traits::NonZeroLayout

pub struct NonZeroLayout(_);

A non-empty layout which can be allocated.

Methods

impl NonZeroLayout

pub fn new<T>() -> Option<Self>

Create the layout for a type.

This succeeds exactly if the type is not a zero-sized type. Otherwise this constructor returns None.

pub fn from_layout(layout: Layout) -> Option<Self>

Creates a non-empty layout if the given layout is not empty.

pub fn size(&self) -> NonZeroUsize

Return the size of the layout.

pub fn align(&self) -> usize

Return the alignment of the layout.
