Functions

func DrainClose

func DrainClose(reader io.Reader) (*bytes.Buffer, error)

DrainClose will read all bytes of an io.Reader into a bytes.Buffer, to allow it to be used multiple times.

If the reader is a *bytes.Buffer, a new bytes.Buffer will be returned from its backing []byte slice.

It will also attempt to Close any provided reader, if it implements the io.Closer iface.

func TryClose

func TryClose(maybeClosers ...interface{})

TryClose tries to cast all provided params to io.Closer, and, if successful, calls Close on each.
