Async/await server pt.4 - timeouts

Dodgy Coding   |   8 views   |   2020-03-21

A gentle exploration of building a identd for Linux using async/await and tokio 0.2. This part demonstrates halting an await after a configurable time limit, both using tokio's timeout() helper and with the select! macro from the futures crate.

Async and its alternatives

Dodgy Coding   |   7 views   |   2019-10-19

Rust libraries come in a variety of API styles and futures are just one option. In this video we compare and contrast four styles from three crates: 1. Synchronous blocking functions (websocket) 2. Single thread reactor (ws-rs) 3. Non-blockin...

Type erasure in Rust/C FFI — structs, generics, trait objects

Dodgy Coding   |   22 views   |   2019-08-18

Exploring how to create data structures that are owned by C and pass pointers back to Rust to operate on them. This is easy for a basic struct but when you introduce generics or traits, things get interesting. Content warning: inadvisable C code.

Experiments with tokio’s lines() function, fold(), and a custom multi-stage future with inner futures and the try_ready macro. With this episode, we are now up to four sub-optimal ways to count the number of lines in a file.

Making a leaf future for tokio

Dodgy Coding   |   16 views   |   2019-06-30

I play around with a standalone future to see how the tokio executor’s polling works in practice. I then adapt a callback-based API to work with futures, including a full implementation of a leaf future that transitions from NotReady to Ready.
