From 99ef0307e75fecc469f63a82bb72d1b697e14fff Mon Sep 17 00:00:00 2001 From: Stefan Majewsky Date: Wed, 7 Feb 2018 19:58:03 +0100 Subject: finish moving towards new auto-generated Headers implementation Everything in one package once more. The bigger API in *this* package is worth it when we don't have to expose guts to cross package boundaries. --- headers/uint64.go | 120 ------------------------------------------------------ 1 file changed, 120 deletions(-) delete mode 100644 headers/uint64.go (limited to 'headers/uint64.go') diff --git a/headers/uint64.go b/headers/uint64.go deleted file mode 100644 index 6e8668b..0000000 --- a/headers/uint64.go +++ /dev/null @@ -1,120 +0,0 @@ -/****************************************************************************** -* -* Copyright 2018 Stefan Majewsky -* -* Licensed under the Apache License, Version 2.0 (the "License"); -* you may not use this file except in compliance with the License. -* You may obtain a copy of the License at -* -* http://www.apache.org/licenses/LICENSE-2.0 -* -* Unless required by applicable law or agreed to in writing, software -* distributed under the License is distributed on an "AS IS" BASIS, -* WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. -* See the License for the specific language governing permissions and -* limitations under the License. -* -******************************************************************************/ - -package headers - -import ( - "strconv" -) - -//Uint64 is a helper type that provides type-safe access to a Swift header -//whose value is an unsigned integer.
