Enum finestra::StateOrRaw

pub enum StateOrRaw<T> {
    Raw(T),
    State(State<T>),
}

A convenient wrapper for State or the “raw” value. A bunch of APIs let you call them with either of them, and this wrapper provides easy Into implementations.

Variants

Raw(T)

A raw value is a value that is applied once, but can’t be updated using the State pattern.

State(State<T>)

This value is reacted by Finestra, and potentially you, by updating the used value (such as the text of a Label).

Implementations

impl<T> StateOrRaw<T>

pub fn with<F: FnOnce(&T) -> R, R>(&self, f: F) -> R

Get the value within, by using a visitor method.

let state = StateOrRaw::Raw("Hello, world!".to_string());

state.with(|value| {
    println!("Value is: {value}");
});

pub fn clone_inner(&self) -> T

where T: Clone,

Clone the inner value. Note: you can also use StateOrRaw::with() if you only need a temporary reference.

let value = StateOrRaw::Raw("Hello, world!".to_string());
let cloned: String = value.clone_inner();

pub fn as_state(&self) -> Option<State<T>>

Get the State if applicable, otherwise None.
