Parser

Struct Parser 

Source
pub struct Parser;
Expand description

Canonical QQL parser facade.

Production parsing is only the hand-written AST lowerer (lexer → tokens → typed AST). There is no parallel PEG/pest frontend in this crate: language/v1/grammar.pest is the language contract for docs and CI (qql-grammar-gen), not a runtime dependency of qql-core.

Implementations§

Source§

impl Parser

Source

pub fn parse(input: &str) -> Result<Stmt, QqlError>

Source

pub fn parse_all(input: &str) -> Result<Vec<Stmt>, QqlError>

Source

pub fn parse_value(input: &str) -> Result<Value, QqlError>

Parse a standalone literal value (string, number, boolean, null, list, or dict).

Errors if parsing fails or if unexpected trailing tokens exist after the value.
