Struct LexBuf 

pub struct LexBuf<'a> {
    pub source: Rc<RefCell<&'a str>>,
    pub line: Rc<RefCell<usize>>,
    pub col: Rc<RefCell<usize>>,
    pub idx: Rc<RefCell<usize>>,
    pub empty: Rc<RefCell<bool>>,
}

A buffer for lexing.

This is a wrapper around a string slice that stores the current state of the lexer.

Lexing functions are provided with a buffer, which is normally automatically generated from an input string. Thus you would rarely need to use this struct directly.

Fields

source: Rc<RefCell<&'a str>>

line: Rc<RefCell<usize>>

col: Rc<RefCell<usize>>

idx: Rc<RefCell<usize>>

empty: Rc<RefCell<bool>>

Implementations

impl<'a> LexBuf<'a>

pub fn share(&self) -> Self

impl<'a> LexBuf<'a>

pub fn new(source: impl Into<LexBuf<'a>>) -> Self

Trait Implementations

impl<'a> From<&'a String> for LexBuf<'a>

fn from(source: &'a String) -> Self

Converts to this type from the input type.

impl<'a> From<&'a str> for LexBuf<'a>

fn from(value: &'a str) -> Self

Converts to this type from the input type.
