Latest change 5a1781679346dc042a413c85c2ddfc034f219ae0 - feat(sql): lexer + parser for a SQL subset (AST) by Ólafur Búi Ólafsson

//! SQL lex/parse errors, with the character offset where they occurred.

use std::fmt;

/// A SQL failure: a human-readable message plus the 0-based character position
/// in the input where lexing or parsing gave up. Malformed input always yields
/// one of these — never a panic.
