Crate stdio_override

Stdio-Override

This crate provides a library for overriding Stdio file descriptors.
It provides a Guard for the replacement so that when the guard is dropped the file descriptors are switched back and the replacement File Descriptor will be closed.

** Trying to replace an std File Descriptor twice will result in a panic **

Notice: When trying to use this in tests you must run with cargo test -- --nocapture otherwise it will redirect stdout/stderr again.

This library is made to be intuitive and easy to use.

Examples

    use stdio_override::StdoutOverride;
    use std::{fs, mem};
    let file_name = "./test.txt";
    let guard = StdoutOverride::override_file(file_name).unwrap();
     println!("Isan to Stdout!");

    let contents = fs::read_to_string(file_name).unwrap();
    assert_eq!("Isan to Stdout!\n", contents);
    mem::drop(guard);
    println!("Outside!");

Structs

StdoutOverride	Override the Stdout File Descriptor safely.
StdoutOverrideGuard	A Guard over the Stdout change. when this guard is dropped stdout will go back to the original, and the file will be closed.
