Struct DecodeOptions 

pub struct DecodeOptions {
    pub beam: f32,
    pub max_active: usize,
    pub min_active: usize,
}

How wide to search.

Fields

beam: f32

Tokens worse than the frame’s best by more than this are dropped.

In nats, since the scores are. f32::INFINITY searches exhaustively, which the tests compare against.

max_active: usize

A hard cap on the tokens kept per frame, applied after beam.

This is what bounds the work when the beam turns out to be too generous for a confusable stretch of audio.

min_active: usize

A floor under the same cap: the beam is never tightened below this many tokens, so a confident frame does not narrow the search to nothing.

Implementations

impl DecodeOptions

pub fn exhaustive() -> Self

No beam and no cap: every path is kept.

The oracle the decoders are tested against searches everything, so this setting is the one that makes the two comparable.
