Struct VerifyWorkspace

Source

pub struct VerifyWorkspace<F: Field> { /* private fields */ }

Expand description

Reusable parity scratch space for repeated verify calls.

This helper keeps the parity buffer allocation outside of verify so repeated callers can naturally take the verify_with_buffer fast path without having to manage Vec<Vec<_>> details themselves.

Implementations§

Source §

impl<F: Field> VerifyWorkspace<F>

Source

pub fn new(codec: &ReedSolomon<F>, shard_len: usize) -> Self

Create a new workspace with parity buffers sized for the given codec and shard length.

Source

pub fn parity_shards(&self) -> usize

Returns the number of parity shard buffers.

Source

pub fn shard_len(&self) -> Option<usize>

Returns the current shard buffer length, or None if there are no parity shards.

Source

pub fn resize(&mut self, codec: &ReedSolomon<F>, shard_len: usize)

Resize parity buffers to match the given codec and shard length.
