Trait FrameAllocator 

pub unsafe trait FrameAllocator<S>
where
    S: PageSize,
{
    // Required method
    fn allocate_frame(&mut self) -> Option<PhysFrame<S>>;
}

A trait for types that can allocate a frame of memory.

Safety

The implementer of this trait must guarantee that the allocate_frame method returns only unique unused frames. Otherwise, undefined behavior may result from two callers modifying or deallocating the same frame.

Required Methods

fn allocate_frame(&mut self) -> Option<PhysFrame<S>>

Allocate a frame of the appropriate size and return it if possible.

Dyn Compatibility

This trait is dyn compatible.

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