Expand description

A trait that defines information necessary to determine the size and alignment of objects within a slab.

Required Methods§

Source

fn size(&self) -> u64

The size in bytes of a single element.

This is the smallest size that this allocator can allocate, and all allocations must have a byte size that is a multiple of this value.

Source

fn elements_per_slot(&self) -> u32

The number of elements that make up a single slot.

Source

fn buffer_usages(&self) -> BufferUsages

The wgpu buffer usages that the slab allocator will specify when creating buffers.

BufferUsages::COPY_DST and BufferUsages::COPY_SRC are always included, regardless of what you specify here.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
