Crate 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 create a parseable table (rather than the standard HTML output). Please see here 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

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);
    }
}

Structs

Error

Error when parsing trfr text.

Reader

Record

The record fields in a trf table

RecordsIntoIter

An owned iterator over the records of a refer file.

RecordsIter

A borrowed iterator over the records of a refer file.

Enums

ErrorKind

Specific errors that can happen.

Flag

If you passed -d, use D, and if you passed -ngs, then you want Ngs. This leads to a slight modification in the parsing.

Type Aliases

Result

A type alias for Result<T, trfr::Error>.
