Struct LineSource

Source 
pub struct LineSource<R>
where
    R: BufRead,
{ /* private fields */ }
Expand description

Source reading stream line by line.

It is a wrapper for BufRead. You can create LineSource from any type implementing BufRead.

Implementations§

Source§

impl<R> LineSource<R>
where R: BufRead,

Source

pub fn new(reader: R) -> LineSource<R>

Creates a LineSource by specified BufRead.

Trait Implementations§

Source§

impl<'a> From<&'a str> for LineSource<BufReader<&'a [u8]>>

You can create LineSource from &str. Since &[u8] is a Read, BufRead can be easily created by wrapping using BufReader.

Source§

fn from(s: &'a str) -> LineSource<BufReader<&'a [u8]>>

Converts to this type from the input type.
Source§

impl<R> Source<R> for LineSource<R>
where R: BufRead,

Source§

fn next_token(&mut self) -> Option<&str>

Gets a next token.

Source§

fn is_empty(&mut self) -> bool

Check if tokens are empty

Source§

fn next_token_unwrap(&mut self) -> &str

Force gets a whitespace-splitted next token.
