    Tokio1,
    AsyncStd1,
}

Available on crate feature sqlite only.

Enumeration for picking a runtime implementation.

Variants

AsyncStd1

Available on crate feature async-std_1 only.

async-std 1.0 runtime.

Implementations

impl Runtime

pub async fn timeout<F>( &self, duration: Duration, future: F, ) -> Option<<F as Future>::Output>

where F: Future,

Available on crate feature mysql only.

Requires a Future to complete before the specified duration has elapsed.

If the future completes before the duration has elapsed, then the completed value is returned. Otherwise, an error is returned and the future is canceled.

pub async fn spawn_blocking<F, R>(&self, f: F) -> Result<R, SpawnBlockingError>

where F: FnOnce() -> R + Send + 'static, R: Send + 'static,

Available on crate feature mysql only.

Runs the given closure on a thread where blocking is acceptable.

Errors

See SpawnBlockingError for details.

pub fn spawn_blocking_background<F>( &self, f: F, ) -> Result<(), SpawnBlockingError>

where F: FnOnce() + Send + 'static,

Available on crate feature mysql only.

Runs the given closure on a thread where blocking is acceptable.

It works similar to Runtime::spawn_blocking() but doesn’t return a Future and is meant to be used for background tasks.

Errors

See SpawnBlockingError for details.

Trait Implementations

impl Clone for Runtime

fn clone(&self) -> Runtime

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Runtime

impl Debug for Runtime

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

Formats the value using the given formatter.

impl Eq for Runtime

impl PartialEq for Runtime

fn eq(&self, other: &Runtime) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
