Struct cassandra_cpp::CassFuture

pub struct CassFuture<T> { /* private fields */ }

A future representing the result of a Cassandra driver operation.

On success, returns a result of type T. On failure, returns a Cassandra error.

When constructing this take care to supply the correct type argument, since it will be used to control how the result is extracted from the underlying Cassandra driver future (see Completable).

Implementations

impl<T: Completable> CassFuture<T>

pub fn wait(self) -> Result<T>

Synchronously executes the CassFuture, blocking until it completes.

Trait Implementations

impl<T: Debug> Debug for CassFuture<T>

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

Formats the value using the given formatter.

impl<T> Drop for CassFuture<T>

fn drop(&mut self)

Drop this CassFuture.

This also drops its reference to the FutureTarget, but if we’re waiting to be called back the FutureState::Awaiting holds another reference to the target, which keeps it alive until the callback fires.

impl<T: Completable> Future for CassFuture<T>

A Cassandra future is a normal Rust future.

type Output = Result<T>

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output>

Attempt to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
