[−][src]Struct hetero_container::VacantEntry
A view into an vacant entry in a HeteroContainer
.
It is part of the Entry
enum.
Implementations
impl<'a, V: 'static> VacantEntry<'a, V>
[src]
pub fn insert(self, default: V) -> &'a mut V
[src]
Sets the value of the entry with the VacantEntry's type, and returns a mutable reference to it.
Examples
use hetero_container::{HeteroContainer, Entry}; let mut container: HeteroContainer = HeteroContainer::new(); if let Entry::Vacant(o, _) = container.entry::<i32>() { o.insert(37); } assert_eq!(container.get::<i32>(), Some(&37));
pub fn key(&self) -> &TypeId
[src]
Gets a reference to the key that would be used when inserting a value
through the VacantEntry
.
Examples
use hetero_container::HeteroContainer; use std::any::TypeId; let mut container: HeteroContainer = HeteroContainer::new(); assert_eq!(container.entry::<i32>().key(), &TypeId::of::<i32>());
