Guards environment.

Required Associated Types

type Error: Display + Send + Sync + 'static

Error type.

Required Methods

fn runtime_version<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<RuntimeVersion, Self::Error>> + Send + 'async_trait>>

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

Return current runtime version.

Provided Methods

fn now(&self) -> Instant

Return current time.

fn sleep<'life0, 'async_trait>( &'life0 mut self, duration: Duration, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

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

Sleep given amount of time.

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

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