Trait AddrTranslator 

pub trait AddrTranslator: Sync {
    // Required method
    fn virt_to_phys(&self, va: usize) -> Option<usize>;
}

Address translator used by allocators to reason about physical addresses.

Implementations should provide a stable virtual-to-physical mapping for the allocator-managed address range.

Examples

use buddy_slab_allocator::AddrTranslator;

struct SimpleMapper;

impl AddrTranslator for SimpleMapper {
    fn virt_to_phys(&self, va: usize) -> Option<usize> {
        // Identity mapping for this example
        Some(va)
    }
}

Required Methods

fn virt_to_phys(&self, va: usize) -> Option<usize>

Translate a virtual address to a physical address.

Returns None if the address is not valid or not mapped.
