Trait r3::bag::Bag

pub trait Bag: Sealed + Copy {
    // Required methods
    fn get<T>(&self) -> Option<&T>
       where T: 'static;
    fn get_mut<T>(&mut self) -> Option<&mut T>
       where T: 'static;

    // Provided method
    fn insert<T>(self, head: T) -> (T, Self)
       where T: 'static { ... }
}

A heterogeneous collection to store property values.

Required Methods

fn get<T>(&self) -> Option<&T>where T: 'static,

Borrow a T if it’s included in self.

fn get_mut<T>(&mut self) -> Option<&mut T>where T: 'static,

Mutably borrow a T if it’s included in self.

Provided Methods

fn insert<T>(self, head: T) -> (T, Self)where T: 'static,

Insert an item and return a new impl Bag.

For const fn-ness, this method can’t have a provided implementation.
