DecoderScratch

mfsk_core::fec::qra::code

Struct DecoderScratch 

Source 
pub struct DecoderScratch { /* private fields */ }
Expand description

Reusable scratch buffers for the BP decoder. Allocated once per QraCode and reused across decode calls — these arrays are sized in O(NMSG · M) floats which is non-trivial (~55 kB for Q65), so caller-side reuse matters.

Implementations§

Source§

impl DecoderScratch

Source

pub fn for_code(code: &QraCode) -> Self

Allocate scratch for the given code. Cheap to keep on a worker or thread-local for the lifetime of a decoding session.
