Function parse_next_statement_into 

pub fn parse_next_statement_into(
    source: &[u8],
    offset: usize,
    limits: &Limits,
    arena: Ast,
) -> Result<ParsedStatement, ParseError>

Parses one statement into an arena the caller supplies.

The same parse as parse_next_statement, with the arena handed in rather than made. A caller that compiles statement after statement keeps one and gets its capacity back on every parse after the first, which on SELECT 1 is most of what a parse costs.

@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
