[−][src]Struct liquid_value::object::OccupiedEntry
An occupied Entry. It is part of the Entry
enum.
Methods
impl<'a> OccupiedEntry<'a>
[src]
pub fn key(&self) -> &KString
[src]
Gets a reference to the key in the entry.
Examples
use liquid_value::object::Entry; let mut map = liquid_value::object::Object::new(); map.insert("liquid".into(), liquid_value::value!(12)); match map.entry("liquid") { Entry::Occupied(occupied) => { assert_eq!(occupied.key(), &"liquid"); } Entry::Vacant(_) => unimplemented!(), }
pub fn get(&self) -> &Value
[src]
Gets a reference to the value in the entry.
Examples
use liquid_value::object::Entry; let mut map = liquid_value::object::Object::new(); map.insert("liquid".into(), liquid_value::value!(12)); match map.entry("liquid") { Entry::Occupied(occupied) => { assert_eq!(occupied.get(), &liquid_value::value!(12)); } Entry::Vacant(_) => unimplemented!(), }
pub fn get_mut(&mut self) -> &mut Value
[src]
Gets a mutable reference to the value in the entry.
Examples
use liquid_value::object::Entry; let mut map = liquid_value::object::Object::new(); map.insert("liquid".into(), liquid_value::value!([1, 2, 3])); match map.entry("liquid") { Entry::Occupied(mut occupied) => { occupied.get_mut().as_array().unwrap(); } Entry::Vacant(_) => unimplemented!(), }
pub fn into_mut(self) -> &'a mut Value
[src]
Converts the entry into a mutable reference to its value.
Examples
use liquid_value::object::Entry; let mut map = liquid_value::object::Object::new(); map.insert("liquid".into(), liquid_value::value!([1, 2, 3])); match map.entry("liquid") { Entry::Occupied(mut occupied) => { occupied.into_mut().as_array().unwrap(); } Entry::Vacant(_) => unimplemented!(), }
pub fn insert(&mut self, value: Value) -> Value
[src]
Sets the value of the entry with the OccupiedEntry
's key, and returns
the entry's old value.
Examples
use liquid_value::object::Entry; let mut map = liquid_value::object::Object::new(); map.insert("liquid".into(), liquid_value::value!(12)); match map.entry("liquid") { Entry::Occupied(mut occupied) => { assert_eq!(occupied.insert(liquid_value::value!(13)), liquid_value::value!(12)); assert_eq!(occupied.get(), &liquid_value::value!(13)); } Entry::Vacant(_) => unimplemented!(), }
pub fn remove(self) -> Value
[src]
Takes the value of the entry out of the map, and returns it.
Examples
use liquid_value::object::Entry; let mut map = liquid_value::object::Object::new(); map.insert("liquid".into(), liquid_value::value!(12)); match map.entry("liquid") { Entry::Occupied(occupied) => { assert_eq!(occupied.remove(), liquid_value::value!(12)); } Entry::Vacant(_) => unimplemented!(), }
