Struct UnsafeScanner

Source 
pub struct UnsafeScanner<R> { /* private fields */ }
Expand description

Same API as Scanner but nearly twice as fast, using horribly unsafe dark arts REQUIRES Rust 1.34 or higher

Implementations§

Source§

impl<R: BufRead> UnsafeScanner<R>

Source

pub fn new(reader: R) -> Self

Source

pub fn token<T: FromStr>(&mut self) -> T

This function should be marked unsafe, but noone has time for that in a programming contest. Use at your own risk!
