Struct BlockPool 

pub struct BlockPool { /* private fields */ }

Fixed-capacity physical-page allocator with reference counts.

Both vectors are fully sized during cold construction. Hot operations only mutate elements or the existing vector length; free has capacity physical_blocks, so push cannot reallocate.

Implementations

impl BlockPool

pub fn new(physical_blocks: u32) -> Self

pub fn allocate(&mut self) -> Result<u32, PoolError>

pub fn retain(&mut self, block: u32) -> Result<(), PoolError>

pub fn release(&mut self, block: u32) -> Result<(), PoolError>

pub fn ref_count(&self, block: u32) -> Option<u32>

pub fn free_count(&self) -> usize

pub fn writable(&mut self, current: u32) -> Result<CopyOnWrite, PoolError>
