Struct LatticeDecodeOptions 

pub struct LatticeDecodeOptions {
    pub search: DecodeOptions,
    pub lattice_beam: f32,
}

How wide to search, and how much of what was found to keep.

Fields

search: DecodeOptions

The beam the search itself runs under.

lattice_beam: f32

Paths worse than the best by more than this are dropped from the lattice.

Separate from search.beam, and usually smaller: the search beam has to be generous because a path that looks bad now may win later, while the lattice beam judges finished paths and can afford to be strict. f32::INFINITY keeps everything the search saw.

Implementations

impl LatticeDecodeOptions

pub fn exhaustive() -> Self

No beam anywhere: the lattice is the whole of graph ∘ dense.

What the tests compare against, since it is the only setting under which the lattice and the composition are the same object.
