interfaceGUID
interfaceGUID exposes a single function CalculateGUID which calculates a
unique deterministic value based on the type provided. It is to be used when
communicating with remote services to quickly assert common knowledge before
starting to communicate, for example via encoding/gob.
Example
type MyService interface {
...
}
guid := interfaceGUID.CalculateGUID(reflect.TypeOf((*MyService)(nil)).Elem())
// Then compare the string with the remote service.

Functions ¶
func Calculate ¶
Calculate returns the hex encoded string of the SHA-256 hash of a reflected type, normally an interface.
The reflected type is traversed recursively up to all native types referenced. The value is dependent on the referenced type names, methods and their order. The name of the type itself is not taken in account.
The purpose of this function is to get into a quick common agreement between two remote parties, so that follow up communication can be done with gob or another communication mechanism.
See test cases for more details.
Example ¶
type Foo interface {
Baz1(int) error
Baz2()
}
fmt.Printf("%s\n", Calculate(reflect.TypeOf((*Foo)(nil)).Elem()))
Output: ee2fbefc01ff399e106213e5eab0f3a36c245f195195bd36a2058c115637e05d
