[−][src]Struct wee_alloc::WeeAlloc
A wee allocator.
Safety
When used in unix environments, cannot move in memory. Typically not an
issue if you're just using this as a static
global allocator.
Methods
impl<'a> WeeAlloc<'a>
[src]
pub const INIT: Self
[src]
An initial const
default construction of a WeeAlloc
allocator.
This is usable for initializing static
s that get set as the global
allocator.

[src]
unsafe fn alloc_zeroed(&self, layout: Layout) -> *mut u8
1.28.0[src]
Behaves like alloc
, but also ensures that the contents are set to zero before being returned. Read more
