# IO Test Util

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

# Usage

### In your Cargo.toml:

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

### In your test:

```rust
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());
}
```
