Struct Grammar 

pub struct Grammar;

Grammar provides methods to parse SQL constructs into CST segments.

Each parse method returns Option<Segment> — None means the construct was not found at the current position, and the cursor is left unchanged (backtracking).

Implementations

impl Grammar

pub fn parse_file<'a>(ctx: &mut ParseContext<'a>) -> Segment

Parse a complete SQL file: zero or more statements.

pub fn parse_statement<'a>(ctx: &mut ParseContext<'a>) -> Option<Segment>

Parse a single statement (terminated by ; or EOF).

pub fn parse_expression<'a>(ctx: &mut ParseContext<'a>) -> Option<Segment>

Parse an expression. This uses a simple precedence climbing approach.
