Enum Dispatch 

pub enum Dispatch {
    Inline,
    SpawnBlocking,
}

How BlockingSink hands off calls to the wrapped SyncProjectionSink.

Variants

Inline

Run the sync method inline on the async worker.

Safe only when the method is guaranteed to return in a few hundred microseconds or less. Anything else blocks the runtime.

SpawnBlocking

Offload to tokio::task::spawn_blocking.

The default. Correct for any sink that touches the file system, synchronous DB drivers, or otherwise blocking code.

Trait Implementations

impl Clone for Dispatch

fn clone(&self) -> Dispatch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Dispatch

impl Debug for Dispatch

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

Formats the value using the given formatter.

impl Eq for Dispatch

impl PartialEq for Dispatch

fn eq(&self, other: &Dispatch) -> 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.
