hyper-timeout

A connect, read and write timeout aware connector to be used with hyper Client.

Problem

At the time this crate was created, hyper did not support timeouts. There is a way to do general timeouts, but no easy way to get connect, read and write specific timeouts.

Solution

There is a TimeoutConnector that implements the hyper::Connect trait. This connector wraps around HttpConnector or HttpsConnector values and provides timeouts.

• The read timeout will start when the underlying stream is first polled for read.
• The write timeout will start when the underlying stream is first polled for write.

Tokio often interleaves poll_read and poll_write calls to handle this bi-directional communication efficiently. Due to this behavior, both the read and write timeouts start at the same time. This means your read timeout can expire while the client is still writing the request to the server. If you are writing large bodies, consider using set_reset_reader_on_write to avoid this behavior.

Usage

Hyper version compatibility:

• The master branch will track on going development for hyper.
• The 0.5 release supports hyper 1.0.
• The 0.4 release supports hyper 0.14.
• The 0.3 release supports hyper 0.13.
• The 0.2 release supports hyper 0.12.
• The 0.1 release supports hyper 0.11.
  • Note: In hyper 0.11, a read or write timeout will return a broken pipe error because of the way tokio_proto::ClientProto works

Assuming you are using hyper 1.0, add this to your Cargo.toml:

[dependencies]
hyper-timeout = "0.5"

See the client example for a working example.
