Module std::os::wasi 1.35.0[−][src]
This is supported on WASI only.
Platform-specific extensions to std
for WASI.
Provides access to platform-level information on WASI, and exposes
WASI-specific functions that would otherwise be inappropriate as
part of the core std
library.
It exposes more ways to deal with platform-specific strings (OsStr
,
OsString
), allows to set permissions more granularly, extract low-level
file descriptors from files and sockets, and has platform-specific helpers
for spawning processes.
Examples
use std::fs::File; use std::os::wasi::prelude::*; fn main() -> std::io::Result<()> { let f = File::create("foo.txt")?; let fd = f.as_raw_fd(); // use fd with native WASI bindings Ok(()) }Run
