Struct abscissa_core::map::VacantEntry 1.0.0[−][src]
A view into a vacant entry in a BTreeMap
.
It is part of the Entry
enum.
Implementations
impl<'a, K, V> VacantEntry<'a, K, V> where
K: Ord,
[src]
K: Ord,
pub fn key(&self) -> &K
1.10.0[src]
Gets a reference to the key that would be used when inserting a value through the VacantEntry.
Examples
use std::collections::BTreeMap; let mut map: BTreeMap<&str, usize> = BTreeMap::new(); assert_eq!(map.entry("poneyland").key(), &"poneyland");
pub fn into_key(self) -> K
1.12.0[src]
Take ownership of the key.
Examples
use std::collections::BTreeMap; use std::collections::btree_map::Entry; let mut map: BTreeMap<&str, usize> = BTreeMap::new(); if let Entry::Vacant(v) = map.entry("poneyland") { v.into_key(); }
pub fn insert(self, value: V) -> &'a mut V
[src]
Sets the value of the entry with the VacantEntry
's key,
and returns a mutable reference to it.
Examples
use std::collections::BTreeMap; use std::collections::btree_map::Entry; let mut map: BTreeMap<&str, u32> = BTreeMap::new(); if let Entry::Vacant(o) = map.entry("poneyland") { o.insert(37); } assert_eq!(map["poneyland"], 37);
