Functions

func OnceValues3

func OnceValues3[T1, T2, T3 any](f func() (T1, T2, T3)) func() (T1, T2, T3)

OnceValues3 returns a function that invokes f only once and returns the values returned by f. The returned function may be called concurrently.

If f panics, the returned function will panic with the same value on every call.

This is copied from sync.OnceValues and extended to for three values.
