Crate whiteread

Crate for reading whitespace-separated values.

The crate defines a trait FromStream, which describes types that can be parsed from whitespace-separated words, which includes eg. integers, tuples, vectors and various adapters.

The definition of whitespace used in this crate is described in SplitAsciiWhitespace.

Examples

Basics

let (s, i): (String, i32) = parse_string("  answer  42 ").unwrap();

Easy reading from stdin.

let x: i32 = parse_line().unwrap();

Efficient reading from stdin (newline-agnostic) with Reader.

let mut i = Reader::from_stdin_naive();
while let Some(f) = i.parse::<Option<f64>>()? {
    println!("{}", f);
}
