Struct DistanceWorkspace 

pub struct DistanceWorkspace { /* private fields */ }

Reusable buffers for repeated lattice distance computations.

The plain convenience functions allocate temporary buffers for each call. Use this workspace when scoring many lattice pairs, such as inside a candidate matrix, to reuse the DP and threshold-search allocations while preserving the same exact results.

Implementations

impl DistanceWorkspace

pub fn new() -> Self

Creates an empty distance workspace.

pub fn try_distance( &mut self, left: &Lattice, right: &Lattice, ) -> Result<usize, DistanceError>

Computes lattice edit distance using this workspace.

pub fn try_distance_with_cutoff( &mut self, left: &Lattice, right: &Lattice, threshold: usize, ) -> Result<Option<usize>, DistanceError>

Computes lattice edit distance up to threshold using this workspace.

pub fn try_damerau_distance( &mut self, left: &Lattice, right: &Lattice, ) -> Result<usize, DistanceError>

Computes lattice Damerau-Levenshtein distance using this workspace.

pub fn try_damerau_distance_with_cutoff( &mut self, left: &Lattice, right: &Lattice, threshold: usize, ) -> Result<Option<usize>, DistanceError>

Computes lattice Damerau-Levenshtein distance up to threshold using this workspace.
