Function std::fs::write

pub fn write<P: AsRef<Path>, C: AsRef<[u8]>>(path: P, contents: C) -> Result<()>
Expand description

Write a slice as the entire contents of a file.

This function will create a file if it does not exist, and will entirely replace its contents if it does.

Depending on the platform, this function may fail if the full directory path does not exist.

This is a convenience function for using File::create and write_all with fewer imports.


use std::fs;

fn main() -> std::io::Result<()> {
    fs::write("foo.txt", b"Lorem ipsum")?;
    fs::write("bar.txt", "dolor sit")?;
