Macro skip_legacy_fields 

skip_legacy_fields!() { /* proc-macro */ }

Scans a match statement for legacy fields which should be skipped.

This is used internally in LDK’s TLV serialization logic and is not expected to be used by other crates.

Wraps a match self {..} statement and scans the fields in the match patterns (in the form ref $field_name: $field_ty) for types marked legacy, skipping those fields.

Specifically, it expects input like the following, simply dropping field3 and the : $field_ty after each field name.

match self {
	Enum::Variant {
		ref field1: option,
		ref field2: (option, explicit_type: u64),
		ref field3: (legacy, u64, {}, {}), // will be skipped
		..
	} => expression
}
