Scanner for different token types

Implementations

impl<'a> TokenScanner<'a>

pub fn new(source: &'a str, position: usize, line: usize, column: usize) -> Self

Create new token scanner

pub fn navigator_mut(&mut self) -> &mut CharNavigator<'a>

Get current navigator state (mutable)

pub const fn navigator(&self) -> &CharNavigator<'a>

Get current navigator state (immutable)

pub fn scan_section_header(&mut self) -> Result<TokenType>

Scan section header like [Script Info]

Errors

Returns an error if character navigation fails.

pub fn scan_style_override(&mut self) -> Result<TokenType>
