Module Octet_stream.Encoding

type known = [
| `Base64
| `Bit7
| `Bit8
| `Binary
| `Quoted_printable
]

Text or binary are the type of the plaintext. For Base64, if the mode is text, '\n' is turned into '\r\n' when encoding, and vice versa.

val of_headers_or_default : ?⁠ignore_base64_for_multipart:bool -> Email_message__.Headers.t -> t

Determine an encoding based on email headers. ignore_base64_for_multipart is useful because some clients can't read RFCs and incorrectly indicate a transfer encoding of base64 for multipart messages.
