Enum sequoia_openpgp::types::DataFormat

source ·
#[non_exhaustive]
pub enum DataFormat { Binary, Text, Unicode, MIME, Unknown(char), }
Expand description

Describes the format of the body of a literal data packet.

See the description of literal data packets Section 5.9 of RFC 4880.

Note: This enum cannot be exhaustively matched to allow future extensions.

§Examples

Construct a new Message containing one text literal packet:

use sequoia_openpgp as openpgp;
use std::convert::TryFrom;
use openpgp::packet::prelude::*;
use openpgp::types::DataFormat;
use openpgp::message::Message;

let mut packets = Vec::new();
let mut lit = Literal::new(DataFormat::Text);
lit.set_body(b"data".to_vec());
packets.push(lit.into());

let message = Message::try_from(packets);
assert!(message.is_ok(), "{:?}", message);

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Binary

Binary data.

This is a hint that the content is probably binary data.

§

Text

Text data.

This is a hint that the content is probably text; the encoding is not specified.

§

Unicode

Text data, probably valid UTF-8.

This is a hint that the content is probably UTF-8 encoded.

§

MIME

👎Deprecated since 1.10.0: Do not use as semantics are unclear

MIME message.

This is defined in Section 5.10 of RFC4880bis.

§

Unknown(char)

Unknown format specifier.
