Struct LineReadStream

pub struct LineReadStream<'a, T: BufRead> {
    pub value: &'a mut T,
    pub cache: Vec<Option<String>>,
}

Fields

value: &'a mut T

cache: Vec<Option<String>>

Implementations

impl<'a, T: BufRead> LineReadStream<'a, T>

pub fn new(item: &'a mut T) -> Self

Trait Implementations

impl<'b, 'a: 'b, T: BufRead> Stream<'a> for LineReadStream<'a, T>

type Item = Option<String>

fn token(&mut self, x: usize) -> StreamResult<Option<String>>

Returns token at x. It’s possible to cache values. FnStream for example caches all tokens returned from getter.

fn junk(&mut self, x: usize)

Basucally same as truncating vector.

fn pos(&self) -> usize

Return stream position, does not used by macro or streams-rs, but might be usefull for someone.
