[$] Canceling asynchronous Rust

Date:
Wed, 24 Sep 2025 15:15:53 +0000

Description:
Asynchronous Rust code has what Rain Paharia calls a " universal cancellation
protocol ", meaning that any asynchronous code can be interrupted in the same
way. They claim
that this is both a useful feature when used deliberately, and a source of
errors when done by accident. They presented
about this problem at RustConf2025 , offering a handful of techniques to 
avoid introducing bugs into
asynchronous Rust code.
