windows: use the default IOCP concurrency value. (#1161) IOCP is initialized with the max number of threads that can be "associated" with the IOCP handle. A thread becomes associated with IOCP when it is woken after selecting. It remains associated with IOCP until the thread sleeps for any reason (blocking I/O, yield, page fault, sleep, ...). Currently, the value is set to 1. However, this was picked mostly because I had no idea what it meant to be "associated" with IOCP and 1 sounded good. It turns out that 0 is lets windows pick a default value (number of cores). This makes much more sense than 1. ref: https://docs.microsoft.com/en-us/windows/win32/fileio/i-o-completion-ports#threads-and-concurrency
Mio is a lightweight I/O library for Rust with a focus on adding as little overhead as possible over the OS abstractions.
API documentation
This is a low level library, if you are looking for something easier to get started with, see Tokio.
To use mio, first add this to your Cargo.toml:
[dependencies] mio = "0.6"
Then, add this to your crate root:
extern crate mio;
The following are specifically omitted from Mio and are left to the user or higher-level libraries.
Currently supported platforms:
There are potentially others. If you find that Mio works on another platform, submit a PR to update the list!
A group of Mio users hang out in the #mio channel on the Mozilla IRC server (irc.mozilla.org). This can be a good place to go for questions.
Interested in getting involved? We would love to help you! For simple bug fixes, just submit a PR with the fix and we can discuss the fix directly in the PR. If the fix is more complex, start with an issue.
If you want to propose an API change, create an issue to start a discussion with the community. Also, feel free to talk with us in the IRC channel.
Finally, be kind. We support the Rust Code of Conduct.
