Implementations

impl RouteSimilarityFunction

pub fn test_similarity( self, a: &[&EdgeTraversal], b: &[&EdgeTraversal], si: &SearchInstance, ) -> Result<bool, SearchError>

tests for similarity between two paths.

Arguments

• a - one route
• b - another route
• si - search instance for these routes

Returns

true if the routes are “similar”

pub fn is_similar(&self, similarity: f64) -> bool

compares a similarity rank against similarity criteria.

Arguments

• similarity - output of this rank_similarity function

Result

true if the ranking meets the similarity criteria

pub fn rank_similarity( &self, a: &[&EdgeTraversal], b: &[&EdgeTraversal], si: &SearchInstance, ) -> Result<f64, SearchError>

ranks the similarity of two routes using this similarity function.

Arguments

• a - one route
• b - another route
• si - search instance for these routes

Returns

the similarity ranking of these routes
