Struct HashMapFunctionCatalog 

pub struct HashMapFunctionCatalog { /* private fields */ }

Minimal in-memory catalog implementation for runtime registration and tests.

Implementations

impl HashMapFunctionCatalog

pub fn set_dialect_name_case( &mut self, dialect: DialectType, name_case: FunctionNameCase, )

Set default function-name casing behavior for a dialect.

pub fn set_function_name_case( &mut self, dialect: DialectType, function_name: impl Into<String>, name_case: FunctionNameCase, )

Set optional per-function casing behavior override for a dialect.

The override key is normalized to lowercase.

pub fn register( &mut self, dialect: DialectType, function_name: impl Into<String>, signatures: Vec<FunctionSignature>, )

Register overloads for a function in a dialect.
