[−][src]Struct druid::Key

pub struct Key<T> { /* fields omitted */ }

A typed key.

This lets you retrieve values of a given type. The parameter implements ValueType. For "expensive" types, this is a reference, so the type for a string is Key<&str>.

Methods

impl<T> Key<T>[src]

pub const fn new(key: &'static str) -> Self[src]

Create a new strongly typed Key with the given string value. The type of the key will be inferred.

Examples

use druid::Key;
use druid::piet::Color;

let float_key: Key<f64> = Key::new("a.very.good.float");
let color_key: Key<Color> = Key::new("a.very.nice.color");
