Struct MinimalDistance

Source 
pub struct MinimalDistance<'a, G: 'a> { /* private fields */ }
Expand description

Calculation of minimum distance from one part of the grammar to another. Similar to multi-source shortest path search in a graph.

Implementations§

Source§

impl<'a, G> MinimalDistance<'a, G>
where G: RuleContainer,

Source

pub fn new(grammar: &'a G) -> Self

Returns a new MinimalDistance for a grammar.

Source

pub fn distances(&self) -> &[(HistoryId, Vec<Option<u32>>)]

Returns distances in order respective to the order of rule iteration.

Source

pub fn minimal_distances(&mut self) -> &[(HistoryId, Vec<Option<u32>>)]

Calculates minimal distance from one parts of the grammar to others. Returns distances in order respective to the order of rule iteration.
