From 53fffa1db7cb04982db8977acd61b808ef60d5a8 Mon Sep 17 00:00:00 2001 From: Ole Troan Date: Tue, 13 Nov 2018 12:36:56 +0100 Subject: API: Add support for type aliases Previously all types are compound. This adds support for aliases, so one can do things like: typedef u32 interface_index; or typedef u8 ip4_address[4]; Change-Id: I0455cad0123fc88acb491d2a3ea2725426bdb246 Signed-off-by: Ole Troan Signed-off-by: Klement Sekera --- src/vpp-api/python/vpp_papi/vpp_serializer.py | 14 +++++++++++++- 1 file changed, 13 insertions(+), 1 deletion(-) (limited to 'src/vpp-api/python/vpp_papi/vpp_serializer.py') diff --git a/src/vpp-api/python/vpp_papi/vpp_serializer.py b/src/vpp-api/python/vpp_papi/vpp_serializer.py index bd0f73803da..a001cca565a 100644 --- a/src/vpp-api/python/vpp_papi/vpp_serializer.py +++ b/src/vpp-api/python/vpp_papi/vpp_serializer.py @@ -79,7 +79,7 @@ class FixedList_u8(object): self.packer = BaseTypes(field_type, num) self.size = self.packer.size - def pack(self, list, kwargs): + def pack(self, list, kwargs = None): """Packs a fixed length bytestring.
