[−][src]Struct hetero_container::VacantEntry

pub struct VacantEntry<'a, V> { /* fields omitted */ }

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>());
