Struct baggie::Baggie

pub struct Baggie<K>where
    K: Eq + Hash,{ /* private fields */ }

struct for collecting values of any type with a string key

Implementations

impl<K> Baggie<K>where
    K: Eq + Hash + Default,

pub fn new() -> Self

Initialize an empty Baggie

pub fn insert<T: 'static>(&mut self, key: K, value: T)

Insert a value into the baggie.

pub fn get<T: 'static, Q>(&self, key: &Q) -> Option<&T>where
    K: Borrow<Q>,
    Q: Eq + Hash + ?Sized,

Get a reference to something in the baggie

pub fn get_mut<T: 'static, Q>(&mut self, key: &Q) -> Option<&mut T>where
    K: Borrow<Q>,
    Q: Eq + Hash + ?Sized,

Get a mutable reference to something in the baggie

pub fn keys(&self) -> Keys<'_, K, Box<dyn Any>>

An iterator visiting all keys in arbitrary order.

pub fn len(&self) -> usize

Number of elements in the map

pub fn clear(&mut self)

Clear the map of all key value pairs; but maintains allocated memory

pub fn is_empty(&self) -> bool

Determine if the Baggie is empty

pub fn contains_key<Q>(&self, key: &Q) -> boolwhere
    K: Borrow<Q>,
    Q: Eq + Hash + ?Sized,

Returns true if the map contains a value for the given key.

pub fn remove<Q>(&mut self, key: &Q) -> Option<Box<dyn Any>>where
    K: Borrow<Q>,
    Q: Eq + Hash + ?Sized,

Remove a key-value pair from the Baggie by key. if the key value pair existed, the raw Box<dyn Any> value will be returned
