TokenScanner

Struct TokenScanner 

Source
pub struct TokenScanner;
Expand description

Locale-aware token scanner used by parser prefilters.

Implementations§

Source§

impl TokenScanner

Source

pub fn scan_locale(text: &str, locale: Locale) -> Vec<Token>

Scan text using the automaton for the provided locale.

Source

pub fn scan(text: &str) -> Vec<Token>

Scan text using the default English automaton.

Source

pub fn contains_type(text: &str, token_type: TokenType) -> bool

Return true if the scanned text contains a token of the given type.

Source

pub fn has_date_hint(text: &str) -> bool

Return true if the text appears to contain date-related hints.

This fast heuristic treats any digits or any scanned token as a hint.
