Struct KvPagePool 

pub struct KvPagePool {
    pub bytes_per_page: usize,
    pub tokens_per_page: u16,
    /* private fields */
}

Pool of fixed-size physical pages. Allocates from a free list; free returns a page so the next allocation can reuse it.

Pool capacity is num_pages * bytes_per_page. Caller owns the underlying byte arena (typically a single large MTLBuffer or host Vec); the pool tracks which IDs are free.

Fields

bytes_per_page: usize

Constants exposed for ergonomics.

tokens_per_page: u16

Implementations

impl KvPagePool

pub fn new(num_pages: u32, bytes_per_page: usize, tokens_per_page: u16) -> Self

pub fn capacity(&self) -> u32

pub fn free_count(&self) -> u32

pub fn used_count(&self) -> u32

pub fn alloc(&mut self) -> Option<KvPageId>

Allocate one page. Returns None when the pool is empty.

pub fn free(&mut self, id: KvPageId)

pub fn descriptor(&self, id: KvPageId) -> &KvPageDesc

pub fn descriptor_mut(&mut self, id: KvPageId) -> &mut KvPageDesc
