Module sql_parser 

Thin wrapper over the sqlparser crate that produces a normalized SqlAnalysis for the guard to evaluate.

Goals:

• Keep sqlparser types out of the guard surface. Everything the guard consumes is a plain String, Vec<String>, or an SqlOperation.
• Extract the four things the guard cares about: the operation class, the referenced tables, the projected columns per table (for SELECT only), and whether a WHERE clause is present.
• Fail-closed on parse errors: returning an Err causes the guard to deny.

Structs

SqlAnalysis

Normalized view of a parsed SQL statement.

Functions

parse

Parse query and return a normalized analysis. Parse errors are returned as [Err(String)] so the guard can build a SqlGuardDenyReason::ParseError from them.
