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 WhiteReader. Stops on error.

let i = std::io::stdin();
let mut i = WhiteReader::new(i.lock());
while let Ok(f) = i.parse::<f64>() {
    println!("{}", f);
}

If you want better error handling in while-let loops, use ok_or_none

Reexports

pub use WhiteError::*;

Structs

Lengthed	Wrapper for reading vector of values represented by a list prepended by a number of elements.
SplitAsciiWhitespace	Fast version of std::str::SplitWhitespace, but with some drawbacks.
WhiteReader	Wrapper for BufRead allowing easy parsing values from a Reader.

Enums

WhiteError

Error which can occur while parsing White object.

Traits

StrExt
StrStream	A streaming iterator yielding borrowed strings.
White	Trait for values that can be parsed from stream of whitespace-separated words.
WhiteResultExt	Trait providing additional methods on `WhiteResult`.

Functions

open	Opens a file, and wraps in WhiteReader
parse_line	Helper function for parsing `White` value from one line of stdin.
