Standard Library Containers Reading the Documentation. Data may be shared by placing it in a reference-counted box or the Rc Bus Service. I've been enjoying reading the Rust standard library code: ithas taught me many Rust-isms, and it's nic… The Rust/Unix code above depends on the system's libc for open() and errno, which are entirely C constructs. Expands to the line number on which it was invoked. Expands to the file name in which it was invoked. Unlike the standard library's traits, however, they are asynchronous — meaning that reading from or writing to a tokio::io type will yield to the Tokio scheduler when IO is not ready, rather than blocking.
