Method WithCancel

test/utils/ktesting/withcontext.go:29–41

WithCancel sets up cancellation in a [TContext.Cleanup] callback and constructs a new TContext where [TContext.Cancel] cancels only the new context.

()

// constructs a new TContext where [TContext.Cancel] cancels only the new
// context.
func (tCtx TContext) WithCancel() TContext {
	ctx, cancel := context.WithCancelCause(tCtx)

	tCtx.Context = ctx
	tCtx.cancel = func(cause string) {
		var cancelCause error
		if cause != "" {
			cancelCause = canceledError(cause)
		}
		cancel(cancelCause)
	}
	return tCtx
}

// WithoutCancel causes the returned context to ignore cancellation of its parent.
// Calling Cancel will only cancel the new context.
