Trait BaseAllocator 

pub trait BaseAllocator {
    // Required methods
    fn init(&mut self, start: usize, size: usize);
    fn add_memory(&mut self, start: usize, size: usize) -> AllocResult;
}

The base allocator trait inherited by other allocator traits.

Provides common initialization methods for all allocator types.

Required Methods

fn init(&mut self, start: usize, size: usize)

Initialize the allocator with a free memory region.

Arguments

• start - Starting address of the memory region
• size - Size of the memory region in bytes

Examples

let mut alloc = MyAllocator;
alloc.init(0x8000_0000, 16 * 1024 * 1024);

fn add_memory(&mut self, start: usize, size: usize) -> AllocResult

Add a free memory region to the allocator.

Arguments

• start - Starting address of the memory region
• size - Size of the memory region in bytes

Returns

Returns Ok(()) on success, or an error if the region overlaps with existing memory.
