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

Reads white-space separated tokens one at a time.

Implementations§

Source§

impl<R: BufRead> Scanner<R>

Source

pub fn new(reader: R) -> Self

Source

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

Use “turbofish” syntax token::() to select data type of next token.

§Panics

Panics if there’s an I/O error or if the token cannot be parsed as T.
