Implementations§

source§

impl<T: Eq + Hash + Copy> TransitiveRelationBuilder<T>

source

pub fn is_empty(&self) -> bool

source

pub fn elements(&self) -> impl Iterator<Item = &T>

source

fn index(&self, a: T) -> Option<Index>

source

fn add_index(&mut self, a: T) -> Index

source

pub fn maybe_map<F, U>(&self, f: F) -> Option<TransitiveRelationBuilder<U>>where F: FnMut(T) -> Option<U>, U: Clone + Debug + Eq + Hash + Copy,

Applies the (partial) function to each edge and returns a new relation builder. If f returns None for any end-point, returns None.

source

pub fn add(&mut self, a: T, b: T)

Indicate that a < b (where < is this relation)

source

pub fn freeze(self) -> TransitiveRelation<T>

Compute the transitive closure derived from the edges, and converted to the final result. After this, all elements will be immutable to maintain the correctness of the result.
