IO Test Util

Collection of utilities for testing failure of io components, e.g. std::io::Read.

Usage

In your Cargo.toml:

[dev-dependencies]
io-test-util = "*"

In your test:

extern crate io_test_util;
use io_test_util::ErrReader;
use std::io::{ErrorKind, Read};

pub fn main() {
    let mut reader = ErrReader::new(ErrorKind::BrokenPipe);
    let res = reader.read(&mut[0; 1]);
    assert!(res.is_err());
}
