Struct State 

pub struct State { /* private fields */ }

The toast queue. The first limit toasts are visible and counting down; the rest wait until a visible one closes.

Implementations

impl State

pub fn new() -> Self

pub fn with_limit(self, limit: usize) -> Self

Sets how many toasts are visible at once. At least one is.

pub fn limit(&self) -> usize

pub fn push(&mut self, toast: Toast) -> Id

Queues a toast and returns its id.

pub fn dismiss(&mut self, id: Id) -> Option<Toast>

Removes a toast, visible or waiting.

pub fn tick(&mut self, now: Instant) -> Vec<Id>

Closes expired toasts and starts the countdown of newly visible ones. Returns the ids that closed.

pub fn update(&mut self, event: Event) -> Option<Output>

pub fn visible(&self) -> impl Iterator<Item = (Id, &Toast)>

The visible toasts, oldest first.

pub fn waiting(&self) -> usize

How many toasts are waiting behind the visible ones.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn needs_tick(&self) -> bool

Whether a visible toast still has to count down.

pub fn ids(&self) -> impl Iterator<Item = Id>

Every queued toast id, visible first, oldest first.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for State

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for State

fn default() -> Self
