Struct InputReader

pub struct InputReader<'a> { /* private fields */ }

A reader over an Input, which may help you in reading chunks of data from the input.

Implementations

impl<'a> InputReader<'a>

pub fn new(input: Input<'a>) -> Self

Creates a new reader from a given input, starting at 0.

pub fn new_at(position: usize, input: Input<'a>) -> Self

Creates a new reader from a given input, starting at a given position.

pub fn read_f64(&mut self) -> f64

Reads a float, advancing one position.

pub fn read_u64(&mut self) -> u64

Reads an usigned integer, advancing one position.

pub fn read_i64(&mut self) -> i64

Reads an integer, advancing one position.

pub fn iter_n_f64(&'a mut self, n: usize) -> impl 'a + Iterator<Item = f64>

Iterates through n floats, advancing the reader.

pub fn iter_n_u64(&'a mut self, n: usize) -> impl 'a + Iterator<Item = u64>

Iterates through n unsigned integers, advancing the reader.

pub fn iter_n_i64(&'a mut self, n: usize) -> impl 'a + Iterator<Item = i64>

Iterates through n integers, advancing the reader.

pub fn read_n_f64(&mut self, n: usize) -> Vec<f64>

Reads n floats, advancing the reader.

pub fn read_n_u64(&mut self, n: usize) -> Vec<u64>

Reads n unsigned integers, advancing the reader.

pub fn read_n_i64(&mut self, n: usize) -> Vec<i64>

Reads n integers, advancing the reader.

pub fn read_f64_into(&mut self, slice: &mut [f64])

Reads n floats into a slice, advancing the reader.

pub fn read_u64_into(&mut self, slice: &mut [u64])

Reads n unsigned integers into a slice, advancing the reader.

pub fn read_i64_into(&mut self, slice: &mut [i64])

Reads n integers into a slice, advancing the reader.
