Struct ParseState 

pub struct ParseState<'a, I> { /* private fields */ }

A struct representing the current parsing state.

Implementations

impl<'a, I> ParseState<'a, I>

pub fn new(input: &'a [I], offset: usize) -> Self

Creates a new parsing state with the given input and offset.

pub fn last_offset(&self) -> Option<usize>

Returns the offset of the previous position, or None if at the beginning.

pub fn current_offset(&self) -> usize

Returns the current offset.

pub fn advance_by(&self, num_chars: usize) -> ParseState<'a, I>

Creates a new parse state with an offset increased by the specified number of characters.

pub fn input(&self) -> &'a [I]

Returns the slice of input starting from the current offset.

pub fn slice_with_len(&self, n: usize) -> &'a [I]

Returns a slice of the input with a specified length starting from the current offset.

Trait Implementations

impl<'a, I: Clone> Clone for ParseState<'a, I>

fn clone(&self) -> ParseState<'a, I>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)
