Struct zng_state_map :: state_map :: OccupiedStateMapEntry Copy item path

impl<'a, T: StateValue> OccupiedStateMapEntry<'a, T>

pub fn get(&self) -> &T

Gets a reference to the value in the entry.

pub fn get_mut(&mut self) -> &mut T

Gets a mutable reference to the value in the entry.

See also into_mut to get a reference tied to the lifetime of the map directly.

pub fn into_mut(self) -> &'a mut T

Converts the entry into a mutable reference to the value in the entry with a lifetime bound to the map itself.

pub fn insert(&mut self, value: T) -> T

Sets the value of the entry, and returns the entry’s old value.

pub fn remove(self) -> T

Takes the value out of the entry, and returns it.
