Module r3_core::utils

Expand description

Utility

This module is exempt from the API stability guarantee unless specified otherwise. It’s exposed mostly because it’s needed by macros.

Re-exports

Zeroable, ZeroableInOption: Re-exported from bytemuck ^1. Zeroable is a marker trait used in HunkDefiner::zeroed and suchlike. It can be derived for struct types. These re-exports are subject to the application-side API stability guarantee.

AlignedStorage
Untyped storage of the specified size and alignment. This is analogous to C++’s std::aligned_storage_t.
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.
ConstAllocator
Compile-time allocator.
Frozen
Erases interior mutability by preventing reference forming.
RawCell
Like UnsafeCell, but implements Sync.

Allocator
const fn-compatible core::alloc::Allocator.
Init
Trait for types having a constant default value. This is essentially a constant version of Default.
Zeroable
Trait for types that can be safely created with zeroed.
ZeroableInOption
Trait for types which are Zeroable when wrapped in Option.
