Types

type CaseName

type CaseName struct {
	Name  string
	Where CasePos
}

CaseName is a case name annotated with a file and line.

func Name

func Name(s string) (c CaseName)

Name annotates a case name with the file and line of the caller.

type CasePos

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

CasePos represents a file and line number.

func (CasePos) String

func (pos CasePos) String() string

type Entry

type Entry struct {
	Name string
	Data func() []byte
	New  func() any // nil if there is no concrete type for this
}
