Documentation

Overview

Package registry provides a way to register options to cmp.Diff.

This is known to be used by:

• go.chromium.org/luci/testing/truth/should.{Resemble,Match}
• go.chromium.org/luci/testing/typed.{Diff,Got}

By default this includes:

• "google.golang.org/protobuf/testing/protocmp".Transform()
• A direct comparison of protoreflect.Descriptor types. These are documented as being comparable with `==`, but by default `cmp` will recurse into their guts.
• A direct comparison of reflect.Type interfaces.
• Functions will compare by their function pointer.

• func GetCmpOptions() []cmp.Option
• func RegisterCmpOption(opt cmp.Option)

Functions

func GetCmpOptions

func GetCmpOptions() []cmp.Option

GetCmpOptions gets a copy of the registry at the time it was called.

func RegisterCmpOption

func RegisterCmpOption(opt cmp.Option)

RegisterCmpOption registers an option to the registry.

RegisterCmpOption will panic if the option is nil. This function does not check for duplicate options because I don't have a good way to do that.
