Trait bump_scope::BumpAllocator

source · 
pub unsafe trait BumpAllocator: Allocator { }
Expand description

An allocator that allows grow(_zeroed), shrink and deallocate calls with pointers that were not allocated by this allocator. This trait is used for BumpBox::into_box to allow safely converting a BumpBox into a Box.

§Safety

  • grow(_zeroed), shrink and deallocate must be ok to be called with a pointer that was not allocated by this Allocator
