Simultaneous open - TCP without a server

Dodgy Coding   |   64 views   |   2020-04-13

A fun quirk of TCP/IP is that you can create a connection without a listening socket. In this video we briefly review how that works, then write a Rust program to trigger the unusual behaviour on real Linux hosts. Code: [https://github.com/thom...

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...

Cancelling Tokio Intervals

Dodgy Coding   |   11 views   |   2019-09-21

A discussion of how futures are given to an async executor and later dropped. Examples of cancelling an Interval stream by erroring out of for_each, and by selecting against another future.

Unicode: The hero or villain? Input Validation of free-form Unicode text in Web Applications

Main kravietz channel   |   12 views   |   2019-09-06

The most difficult fields to validate are so called free text fields", as the most frequent stereotype of web application input valiation goes, becomes even more complicated when the free text contains multi-language Unicode. Unicode is indeed com...

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.

Tokio I/O futures

Dodgy Coding   |   12 views   |   2019-07-07

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.
