Structs

• AllocErrorExperimental
  The AllocError error indicates an allocation failure that may be due to resource exhaustion or to something wrong when combining the given input arguments with this allocator.
• GlobalExperimental
  The global memory allocator.
• Layout
  Layout of a block of memory.
• LayoutError
  The parameters given to Layout::from_size_align or some other Layout constructor do not satisfy its documented constraints.

Statics

• __rust_no_alloc_shim_is_unstable 🔒

Traits

• AllocatorExperimental
  An implementation of Allocator can allocate, grow, shrink, and deallocate arbitrary blocks of data described via Layout.
• GlobalAlloc
  A memory allocator that can be registered as the standard library’s default through the #[global_allocator] attribute.
• WriteCloneIntoRaw 🔒
  Specialize clones into pre-allocated, uninitialized memory. Used by Box::clone and Rc/Arc::make_mut.
