Functions

func GetIgnoreErrors

func GetIgnoreErrors(g Getter) func() string

func GetOrPanic

func GetOrPanic(g Getter) func() string

GetOrPanic curries the result of a Getter invocation: the returned func only ever returns the string component when the error component of the underlying Get() call is nil. If Get() generates an error then the curried func panics.

func SetOrPanic

func SetOrPanic(s Setter) func(v string)

SetOrPanic curries the result of a Setter invocation: the returned func only ever returns normally when the error component of the underlying Set() call is nil. If Set() generates an error then the curried func panics.
