Struct Parser 

pub struct Parser { /* private fields */ }

Source-span-backed parser for converting formulas into an AST.

This is the canonical parser implementation. It owns the formula source and span tokens, avoiding per-token string allocation while preserving source locations for AST nodes.

Implementations

impl Parser

pub fn new<T: AsRef<str>>(formula: T) -> Result<Self, TokenizerError>

Tokenize a formula using the default Excel dialect and prepare it for parsing.

pub fn try_from_formula(formula: &str) -> Result<Self, TokenizerError>

Compatibility alias for Parser::new.

pub fn new_with_dialect<T: AsRef<str>>( formula: T, dialect: FormulaDialect, ) -> Result<Self, TokenizerError>

Tokenize a formula with an explicit dialect and prepare it for parsing.

pub fn from_token_stream(stream: &TokenStream) -> Self

Build a parser from an existing source-backed token stream.

pub fn with_volatility_classifier<F>(self, f: F) -> Self

where F: Fn(&str) -> bool + Send + Sync + 'static,

Provide a function-volatility classifier for this parser. If set, the parser will annotate ASTs with a contains_volatile bit.

pub fn parse(&mut self) -> Result<ASTNode, ParserError>

pub fn builder() -> ParserBuilder
