Trait fera_graph::props::PropGet

pub trait PropGet<K> {
    type Output: Sized;
    fn get(&self, key: K) -> Self::Output;

    fn map<F, O>(self, fun: F) -> Map<Self, F>
    where
        Self: Sized,
        F: Fn(Self::Output) -> O,
    { ... }
    fn by_ref(&self) -> &Self { ... }
}

An abstract property that maps keys in domain K to the corresponding values.

Associated Types

type Output: Sized

Required Methods

fn get(&self, key: K) -> Self::Output

Returns the value associated with key.

Provided Methods

fn map<F, O>(self, fun: F) -> Map<Self, F> where
    Self: Sized,
    F: Fn(Self::Output) -> O, 

Creates a mapped property that maps each property value using fun.

fn by_ref(&self) -> &Self

Returns a reference to this property.
