Types

type ChallengePrivate added in v1.34.0 

type ChallengePrivate struct {
	// contains filtered or unexported fields
}

func (k ChallengePrivate) Public() ChallengePublic

Public returns the ChallengePublic for k. Panics if ChallengePublic is zero.

type ChallengePublic added in v1.34.0 

type ChallengePublic struct {
	// contains filtered or unexported fields
}

ChallengePublic is the public portion of a ChallengePrivate.
