A utility package for Go pointers

== Pointer Resolution

In this package there are helper methods for resolving pointers of primitive types, with a fallback to a default value.

For example, resolving a pointer to a string:

[source,go]

----

import "github.com/noamt/goptr"

goptr.String(nil) // Returns an empty string

goptr.String("foo") // Returns "foo"

goptr.StringOrDefault(nil, "foo") // Returns "foo"

s := "bar"

goptr.StringOrDefault(&s, "foo") // Returns "bar"

----
