[−][src]Struct alloc_traits::NonZeroLayout
A non-empty layout which can be allocated.
Methods
impl NonZeroLayout
[src]
pub fn new<T>() -> Option<Self>
[src]
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>
[src]
Creates a non-empty layout if the given layout is not empty.
pub fn size(&self) -> NonZeroUsize
[src]
Return the size of the layout.
pub fn align(&self) -> usize
[src]
Return the alignment of the layout.
