Available on crate feature full only.

A virtual memory allocator.

Required Methods

fn allocate_contiguous(&self, len: usize) -> Result<RawPage, AllocError>

Allocates count number of contiguous pages.

Errors

Returns an AllocError if the memory could not be allocated. This does not mean there is no free memory, just that is there no region of contiguous memory large enough.

fn allocate_contiguous_at( &self, at: RawPage, len: usize, ) -> Result<RawPage, AllocError>

Allocates count number of contiguous pages with the first frame being at at.

Errors

Returns an AllocError if the memory could not be allocated. This does not mean there is no free memory, just that is there no region of contiguous memory large enough starting at at.

fn deallocate_contiguous(&self, base: RawPage, len: usize)

Deallocates count frames starting at base.

Dyn Compatibility

This trait is dyn compatible.

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