# IO Arg

Conviniently accept either standard streams or file paths in CLI tools written in Rust as arguments.

## Usage

```rust

use io_arg::IoArg;

use clap::Parser;

/// A command line tool taking a required input argument and an optional output argument.

#[derive(Debug, Parser)]

struct Cli {

    /// Path to input file. Set to "-" to use STDIN instead of a file.

    input: IoArg,

    /// Path to output file. Leave out or set to "-" to use STDOUT instead of a file.

    #[structopt(long, short = "o", default_value = "-")]

    output: IoArg,

}

```
