Trait Provider

pub trait Provider {
    // Required method
    fn timers<Q: Query>(&self, query: &mut Q) -> Result;

    // Provided methods
    fn next_expiration(&self) -> Option<Timestamp> { ... }
    fn is_armed(&self) -> bool { ... }
    fn armed_timer_count(&self) -> usize { ... }
    fn for_each_timer<F: FnMut(&Timer) -> Result>(&self, f: F) { ... }
}

A trait for a components that owns at least one timer

Required Methods

fn timers<Q: Query>(&self, query: &mut Q) -> Result

Notifies the query of any timers owned by the provider

The provider should also delegate to subcomponents that own timers as well.

Provided Methods

fn next_expiration(&self) -> Option<Timestamp>

Returns the next Timestamp at which the earliest timer is armed in the provider

fn is_armed(&self) -> bool

Returns true if there are any timers armed

fn armed_timer_count(&self) -> usize

Counts the number of armed timers in the provider

fn for_each_timer<F: FnMut(&Timer) -> Result>(&self, f: F)

Iterates over each timer in the provider and calls the provided function

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
