Module alloc

Expand description

Re-export the allocator2 API for use.

Modules§

alloc: Memory allocation APIs
boxed: The Box<T> type for heap allocation.
collections
vec: A contiguous growable array type with heap-allocated contents, written Vec<T>.

unsize_box: Allows turning a Box<T: Sized, A> into a Box<U: ?Sized, A> where T can be unsizing-coerced into a U.
vec: Creates a Vec containing the arguments.

AllocError: 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.
Global: The global memory allocator.
Layout: Layout of a block of memory.
LayoutError: The LayoutError is returned when the parameters given to Layout::from_size_align or some other Layout constructor do not satisfy its documented constraints.
System: The default memory allocator provided by the operating system.

Allocator: 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.
SliceExt: Slice methods that use Box and Vec from this crate.

alloc^⚠: Allocates memory with the global allocator.
alloc_zeroed^⚠: Allocates zero-initialized memory with the global allocator.
dealloc^⚠: Deallocates memory with the global allocator.
handle_alloc_error: Signals a memory allocation error.
realloc^⚠: Reallocates memory with the global allocator.
