Struct awint_macro_internals::BiMap

pub struct BiMap<P: PtrTrait, T: Clone + Eq + Hash, A> { /* private fields */ }

This is a special purpose structure that can efficiently handle forwards and backwards lookups and maintains the set property. A is associated data that is not hashed or used in equality comparisons.

Iteration over the arena is deterministic.

Implementations

impl<P: PtrTrait, T: Clone + Eq + Hash, A> BiMap<P, T, A>

pub fn new() -> Self

pub fn arena(&self) -> &Arena<P, (T, A)>

pub fn arena_mut(&mut self) -> &mut Arena<P, (T, A)>

Warning: invalidating pointers in the arena can break the BiMap

pub fn contains(&self, t: &T) -> Option<Ptr<P>>

pub fn insert_with<F: FnOnce(Ptr<P>) -> A>(
    &mut self,
    t: T,
    associate: F
) -> Result<Ptr<P>, Ptr<P>>

If t is already contained, it and a are not inserted. Returns None if inserted a new entry (use F to get the new Ptr<P>), else returns the Ptr<P> to an already existing t.

pub fn insert(&mut self, t: T, a: A) -> Result<Ptr<P>, Ptr<P>>

pub fn t_get<B: Borrow<T>>(&self, t: B) -> (Ptr<P>, &(T, A))

pub fn p_get<B: Borrow<Ptr<P>>>(&self, p: B) -> &(T, A)

pub fn a_get_mut<B: Borrow<Ptr<P>>>(&mut self, p: B) -> &mut A
