derefer

Package derefer contains helper routines for simplifying the getting of optional fields of basic type. This allows you to get the value from the pointer even if it is nil, because in this case the zero value of the specified type will be received.

Installation

go get github.com/xorcare/derefer

Examples

Examples of using the library are presented on godoc.org and in the source library code.
