Trait subst::VariableMap

pub trait VariableMap<'a> {
    type Value;

    // Required method
    fn get(&'a self, key: &str) -> Option<Self::Value>;
}

Trait for types that can be used as a variable map.

Required Associated Types

type Value

The type returned by the get() function.

Required Methods

fn get(&'a self, key: &str) -> Option<Self::Value>

Get a value from the map.
