Expand description

Catalog abstraction for dialect-specific function metadata.

Implementations can be backed by generated files, external crates, or runtime-loaded assets.

Required Methods§

Source

fn lookup( &self, dialect: DialectType, raw_function_name: &str, normalized_name: &str, ) -> Option<&[FunctionSignature]>

Lookup overloads for a function name in a given dialect.

raw_function_name should preserve user query casing. normalized_name should be canonicalized/lowercased by the caller.
