Struct Timer

pub struct Timer { /* private fields */ }

The Timer structure is the default Context.

Implementations

impl Timer

pub fn background() -> Self

Create a default, independent timer with no time duration limit.

pub fn todo() -> Self

Create a default, independent timer with no time duration limit.

pub fn with_timeout(timeout: Duration) -> Self

Specify the maximum execution duration for the Timer.

Trait Implementations

impl Clone for Timer

fn clone(&self) -> Timer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Context for Timer

fn timer(&self) -> Timer

return the basic Timer.

fn deadline<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Option<Instant>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

return the deadline time::Instant of this context. return None when this context doesn’t have deadline.

fn cancel<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

cancel this context, then cancel all its childs.

fn is_cancelled<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = bool> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

check whether this context is cancelled or not.

fn is_timeout<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = bool> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

check whether this context is timeout or not.

fn spawn<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Self> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

spawn a new child context.

fn spawn_with_timeout<'life0, 'async_trait>( &'life0 self, timeout: Duration, ) -> Pin<Box<dyn Future<Output = Self> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

spawn a new child context, with a new timeout parameter.

fn handle<'a, 'life0, 'async_trait, Fut, Output>( &'life0 self, fut: Fut, ) -> Pin<Box<dyn Future<Output = Result<Output>> + Send + 'async_trait>>

where Fut: Future<Output = Output> + Send + Sync + 'a + 'async_trait, Output: 'async_trait, Self: 'async_trait, 'a: 'async_trait, 'life0: 'async_trait,

handle a future

impl Debug for Timer

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

Formats the value using the given formatter.

impl Default for Timer

fn default() -> Timer

Returns the “default value” for a type.
