[−][src]Struct abi_stable::std_types::map::RVacantEntry
A handle into a vacant entry in a map.
Implementations
impl<'a, K, V> RVacantEntry<'a, K, V>[src]
pub fn key(&self) -> &K[src]
Gets a reference to the key of the entry.
Example
use abi_stable::std_types::map::{REntry,RHashMap}; let mut map=RHashMap::<u32,u32>::new(); match map.entry(1337) { REntry::Occupied(_)=>{ unreachable!(); } REntry::Vacant(entry)=>{ assert_eq!(entry.key(),&1337); } } assert_eq!( map.get(&1337), None );
pub fn into_key(self) -> K[src]
Gets back the key that was passed to RHashMap::entry.
Example
use abi_stable::std_types::map::{REntry,RHashMap}; let mut map=RHashMap::<String,u32>::new(); match map.entry("lol".into()) { REntry::Occupied(_)=>{ unreachable!(); } REntry::Vacant(entry)=>{ assert_eq!(entry.into_key(),"lol".to_string()); } } assert_eq!( map.get("lol"), None );
pub fn insert(self, value: V) -> &'a mut V[src]
Sets the value of the entry,returning a mutable reference to it.
Example
use abi_stable::std_types::map::{REntry,RHashMap}; let mut map=RHashMap::<String,u32>::new(); match map.entry("lol".into()) { REntry::Occupied(_)=>{ unreachable!(); } REntry::Vacant(entry)=>{ assert_eq!(entry.insert(67),&mut 67); } } assert_eq!( map.get("lol"), Some(&67) );
