Struct Characters

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

A Stream through a str.

The Tokens are chars. Their Locations are relative to the str.

The Stream is terminated with Token::end_of_file() if is_complete, otherwise with Token::incomplete().

Implementations

impl<'a> Characters<'a>

pub fn new(source: &'a str, is_complete: bool) -> Self

Iterate through source.

• is_complete - Determines the Token appended to the end of source. true gives Token::end_of_file(), otherwise Token::incomplete().

pub fn index(&self) -> usize

Returns the current byte index in the str.

Trait Implementations

impl<'a> Stream for Characters<'a>

fn read(&mut self) -> Token

Read a single Token.

fn read_all(self) -> Vec<Token>

where Self: Sized,

Read and return all Tokens upto EndOfFile, which is discarded.
