Crate whiteread [−] [src]
Crate for reading whitespace-separated values.
The crate defines a trait White
, which
describes types that can be parsed from whitespace-separated words,
which includes eg. integers, tuples and vectors.
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
.
Stops on error.
let i = std::io::stdin(); let mut i = Reader::new(i.lock()); while let Ok(f) = i.parse::<f64>() { println!("{}", f); }
If you want better error handling in while-let loops
(stop on end of input, but propagate all the other errors),
use none_on_too_short
