Struct ColumnBufferPool 

pub struct ColumnBufferPool { /* private fields */ }

Implementations

impl ColumnBufferPool

pub fn new() -> Self

pub fn acquire(&self, target: &Type, min_capacity: usize) -> ColumnBuffer

Pop a buffer for target whose capacity() >= min_capacity, preferring the smallest qualifying buffer (best-fit). Falls back to allocating fresh via ColumnBuffer::with_capacity if target is not poolable or no qualifying buffer is in the bucket.

pub fn release(&self, buffer: ColumnBuffer)

Clear buffer and return it to the pool indexed by its type. Drops the buffer if its type is not poolable, or if the bucket is at CAP_PER_TYPE.

pub fn len(&self) -> usize

Total number of buffers currently held across all type buckets. Primarily for tests.

pub fn is_empty(&self) -> bool

true if every bucket is empty. Primarily for tests.

Trait Implementations

impl Default for ColumnBufferPool

fn default() -> Self

Returns the “default value” for a type.
