Struct Parser 

pub struct Parser<'a> { /* private fields */ }

The parser: a lexer, a token buffer, an arena, and a depth charge.

Implementations

impl<'a> Parser<'a>

pub fn new(source: &'a [u8], offset: usize, limits: &'a Limits) -> Parser<'a>

Returns a parser positioned at an offset in the source.

pub fn with_arena( source: &'a [u8], offset: usize, limits: &'a Limits, arena: Ast, ) -> Parser<'a>

Returns a parser that fills an arena the caller supplies.

For a caller that parses one statement after another. The arena is cleared rather than dropped, so the second parse pushes into capacity the first one took - see Ast::clear. Nothing else differs: the arena is filled and handed back exactly as new’s own is.

@param source - the SQL text @param offset - where in it this statement starts @param limits - the limits to enforce @param arena - the arena to fill, cleared first

pub fn into_ast(self) -> Ast

Returns the arena, for a caller that owns the parse.

pub fn source(&self) -> &'a [u8]

Returns the source being parsed.
