pub struct GroupBuilder<'a, K: Hash + Eq, V, S = RandomState> where
    S: BuildHasher,  { /* fields omitted */ }

Builder for a group.

Methods

impl<'a, K: Hash + Eq, V> GroupBuilder<'a, K, V, RandomState>

pub fn build(self) -> Group<'a, K, V, RandomState>

Creates the group.

impl<'a, K: Hash + Eq, V, S: BuildHasher> GroupBuilder<'a, K, V, S>

pub fn capacity(self, capacity: usize) -> GroupBuilder<'a, K, V, S>

Sets the specified capacity for the group.

pub fn signals<F>(self, f: F) -> GroupBuilder<'a, K, V, S> where
    F: FnMut(Option<&K>) + Send + Sync + 'a,

Examples

Group::builder()
    .signals(|k| match k {
        Some(k) => println!("The new active stack is {}.", k),
        None => println!("No active stack."),
    })
    .build();

pub fn build_with_hasher(self, hasher: S) -> Group<'a, K, V, S>
