Enum Entry

pub enum Entry<'a, 'b> {
    Vacant(VacantEntry<'a, 'b>),
    Occupied(OccupiedEntry<'a, 'b>),
}

A view into a single entry in a map, which may either be vacant or occupied. This enum is constructed from the entry method on Amf0Object.

Variants

Vacant(VacantEntry<'a, 'b>)

A vacant Entry.

Occupied(OccupiedEntry<'a, 'b>)

An occupied Entry.

Implementations

impl<'a, 'b> Entry<'a, 'b>

pub fn key(&self) -> &StringCow<'b>

Returns a reference to this entry’s key.

Examples

let mut map = scuffle_amf0::Amf0Object::new();
assert_eq!(map.entry("serde").key(), &"serde");

pub fn or_insert(self, default: Amf0Value<'b>) -> &'a mut Amf0Value<'b>

Ensures a value is in the entry by inserting the default if empty, and returns a mutable reference to the value in the entry.

pub fn or_insert_with<F>(self, default: F) -> &'a mut Amf0Value<'b>

where F: FnOnce() -> Amf0Value<'b>,

Ensures a value is in the entry by inserting the result of the default function if empty, and returns a mutable reference to the value in the entry.

pub fn and_modify<F>(self, f: F) -> Self

where F: FnOnce(&mut Amf0Value<'b>),

Provides in-place mutable access to an occupied entry before any potential inserts into the map.
