Struct ScratchPool 

pub struct ScratchPool { /* private fields */ }

Pool of decoder-internal scratch buffers, reusable across many Decoder::decode_into_with_scratch / decode_rows_with_scratch calls.

Implementations

impl ScratchPool

pub fn new() -> Self

Create an empty pool. The first decode that uses it pays the full allocation cost; subsequent decodes at the same-or-smaller shape reuse the underlying Vecs with zero allocations.

Trait Implementations

impl Debug for ScratchPool

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

Formats the value using the given formatter.

impl Default for ScratchPool

fn default() -> ScratchPool

Returns the “default value” for a type.

impl ScratchPool for ScratchPool

fn bytes_allocated(&self) -> usize

Return the number of bytes currently retained by the pool.

fn reset(&mut self)

Clear reusable allocations or cached state held by the pool.
