# `trfr`

The `trfr` crate is purely for parsing the output of the command line tool `Tandem Repeat Finder` (or `trf`).

The output is generated by passing the `-d` flag to createa parseable table (rather than the standard HTML output). Please see [here](https://github.com/Benson-Genomics-Lab/TRF) for the source code and citation for `trf`.

The API follows that of most mainstream Rust API's (in particular BurntSushi's). It is an iterator API.

# Example

```rust
use std::{error::Error, io, process};

fn example() -> Result<(), Box<dyn Error>> {
    // Build the trfr reader
    // and assuming you are parsing with `-d` flag only
    let mut rdr = trfr::Reader::from_reader(io::stdin(), trfr::Flag::D);
    for result in rdr.records() {
        let record = result?;
        println!("{:?}", record);
    }
    Ok(())
}

fn main() {
    if let Err(err) = example() {
        println!("error running example: {}", err);
        process::exit(1);
    }
}
```
