func Match ¶

func Match(param *dst.Field, registry *config.CarrierRegistry) (config.CarrierDef, string, bool)

Match extracts carrier info from a function parameter. It returns the carrier definition, variable name, and a boolean indicating success.

The function supports:

• Direct types with resolved paths (from NewDecoratorFromPackage)
• Selector expressions (pkg.Type) with path set by decorator
• Pointer types (*T)

Note: This requires type-resolved DST (via NewDecoratorFromPackage). The dst.Ident.Path field must be set for carrier matching to work.

Parameters:

• param: The function parameter field to analyze
• registry: The carrier registry to lookup types

Returns:

• config.CarrierDef: The matched carrier definition
• string: The variable name of the parameter
• bool: true if a carrier was matched, false otherwise
