func Must

func Must[T any](t *testing.T) func(v T, err error) T

Must provides a concise way to handle returned error in cases that "should never happen"©.

This function can be used in test case setup that can be presumed to be correct, but technically may return an error. This function MUST NOT be used to check for test case conditions themselves because it generates a generic, nondescript test error message.

func startServer(addr string) (*server, err)
mustServer := testingx.Must[*server](t)
mustServer(startServer(":8080"))
