[][src]Struct rusoto_core::RusotoFuture

pub struct RusotoFuture<T, E> { /* fields omitted */ }

Future that is returned from all rusoto service APIs.

Mocking

To mock service traits, you can use [RusotoFuture::from_future] to create [RusotoFuture] instance. You can also use the [From] implementation on the [Result] value.

This example is not tested
use std::time::{Duration, Instant};
use futures::prelude::*;
use rusoto_core::RusotoFuture;
use rusoto_s3::*;
use tokio_timer::Delay;

pub struct S3Mock;

impl S3 for S3Mock {
    fn abort_multipart_upload(
        &self,
        _input: AbortMultipartUploadRequest,
    ) -> RusotoFuture<AbortMultipartUploadOutput, AbortMultipartUploadError> {
        unimplemented!();
    }

    // ...

    fn put_object(&self, input: PutObjectRequest) -> RusotoFuture<PutObjectOutput, PutObjectError> {
        if input.bucket == "foo" {
            let deadline = Instant::now() + Duration::from_secs(3);
            let output = PutObjectOutput {
                ..Default::default()
            };
            RusotoFuture::from_future(
                Delay::new(deadline)
                    .map_err(|e| PutObjectError::Unknown(e.to_string()))
                    .map(|_| output)
            )
        } else {
            Err(PutObjectError::Validation("Invalid bucket".to_string())).into()
        }
    }

    // ...
}

Methods

impl<T, E> RusotoFuture<T, E>
[src]

Set the timeout on the future to the provided duration.

Unlike set_timeout this method can be easily chained:

This example is not tested
let future = s3.list_buckets()
    .with_timeout(Duration::from_secs(10));

This is only guaranteed to take effect when called before the future is polled for the first time.

Set the timeout on the future to the provided duration.

This is only guaranteed to take effect when called before the future is polled for the first time.

Clear the timeout on the future.

This is only guaranteed to take effect when called before the future is polled for the first time.

Blocks the current thread until the future has resolved.

This is meant to provide a simple way for non-async consumers to work with rusoto.

Wraps the provided future, mainly to mock the service response.

Caution

This is not intended to be used outside of the test case. In production, [Box] is recommended.
