Now I'm learning that this may panic if a user happens to call my code within async code. That's pretty bad. This makes block_on unsuitable for any library code and the documentation contains no mention of it.

WebbA JoinHandle detaches the associated task when it is dropped, which means that there is no longer any handle to the task, and no way to join on it. This struct is created by the task::spawn and task::spawn_blocking functions. Cancel safety The &mut JoinHandle type is cancel safe. WebbComprehensive Rust ... Another fix would be to tokio::task::spawn_blocking which spawns an actual thread and transforms its handle into a future without blocking the executor. You should not think of tasks as OS threads. They do not map 1 to 1 and most executors will allow many tasks to run on a single OS thread. freezer cooking recipes for crockpotWebbThis crate provides a number of core abstractions for writing asynchronous code: Futures are single eventual values produced by asynchronous computations. Some programming languages (e.g. JavaScript) call this concept “promise”. Streams represent a series of values produced asynchronously.

WebbSearch Tricks. Prefix searches with a type followed by a colon (e.g. fn:) to restrict the search to a given type. Accepted types are: fn, mod, struct, enum, trait, type, macro, and const. Search functions by type signature (e.g. vec -> usize or * -> vec) Search multiple things at once by splitting your query with comma (e.g. str,u8 or String,struct:Vec,test)

Webb21 dec. 2024 · In Rust, this swapping happens when you .await something. When writing async Rust, the phrase “blocking the thread” means “preventing the runtime from swapping the current task”. This can be a major issue because it means that other tasks on the same runtime will stop running until the thread is no longer being blocked.
