Trait Allocator 

trait Allocator<const N: usize> {
    // Required methods
    fn initializer(    ) -> unsafe fn(PhysAddr, usize) -> Result<Pin<Box<Self>>, Error>;
    fn alloc(&mut self, page_count: usize) -> Option<PhysAddr>;
    fn free(&mut self, addr: PhysAddr, page_count: usize);
}

This trait abstracts over different page frame allocator implementations.

Required Methods

fn initializer() -> unsafe fn(PhysAddr, usize) -> Result<Pin<Box<Self>>, Error>

Returns an initializer function that can be used to create an instance of the allocator. The initializer function takes a physical address and the amount of pages needed.

Safety:

• The returned function must only be called with a useable and valid physical address.

fn alloc(&mut self, page_count: usize) -> Option<PhysAddr>

fn free(&mut self, addr: PhysAddr, page_count: usize)

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
