[][src]Struct std::collections::btree_map::DrainFilter

pub struct DrainFilter<'a, K, V, F> where
    F: 'a + FnMut(&K, &mut V) -> bool,
    K: 'a,
    V: 'a, 
{ /* fields omitted */ }
🔬 This is a nightly-only experimental API. (btree_drain_filter #70530)

An iterator produced by calling drain_filter on BTreeMap.
