Struct VecPool 

pub struct VecPool { /* private fields */ }

A simple frame pool backed by a Vec of reusable buffers.

Stores up to capacity buffers and returns them to callers via FramePool::acquire. When exhausted, acquire returns None and the caller allocates a new buffer directly.

Thread Safety

All access is protected by a Mutex, making VecPool safe to share across threads via Arc<VecPool>.

Examples

use ff_common::VecPool;

let pool = VecPool::new(32);
assert_eq!(pool.available(), 0); // pool starts empty

Implementations

impl VecPool

pub fn new(capacity: usize) -> Arc<Self>

Creates a new pool with the given maximum buffer count.

Arguments

• capacity - Maximum number of buffers to retain in the pool.

pub fn capacity(&self) -> usize

Returns the maximum number of buffers this pool will retain.

pub fn available(&self) -> usize

Returns the number of buffers currently available in the pool.

Examples

use ff_common::VecPool;

let pool = VecPool::new(8);
assert_eq!(pool.available(), 0);

Trait Implementations

impl Debug for VecPool

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FramePool for VecPool

fn acquire(&self, size: usize) -> Option<PooledBuffer>

Acquires a buffer of at least the specified size from the pool.

fn release(&self, buffer: Vec<u8>)

Returns a buffer to the pool.
