Documentation

Overview

Package mustr is guaranteed to only export symbols starting with word Must or R. It is intended to be used in tests via dot-import:

import (
    "testing"

    . "import.name/testing/mustr"
)

func example() (int, error)

func Test(t *testing.T) {
    _ = Must(t, R(example()))
}

Test fails immediately if example returns an error.

• func Must[Value any](t internal.Testing, r internal.Result[Value]) Value
• func R[Value any](x Value, err error) internal.Result[Value]

Functions

func Must

func Must[Value any](t internal.Testing, r internal.Result[Value]) Value

Must calls t.Fatal() with the error (the second value of the result) if it is non-nil, otherwise it returns the first value of the result.

func R

func R[Value any](x Value, err error) internal.Result[Value]

R can be used to wrap the result of a function call which returns two values, the second of which is an error.
