Enum sequoia_openpgp::types::DataFormat

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

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)

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.

Implementations

impl DataFormat

pub fn variants() -> impl Iterator<Item = Self>

Returns an iterator over all valid variants.

Returns an iterator over all known variants. This does not include the DataFormat::Unknown variants.

Trait Implementations

impl Clone for DataFormat

fn clone(&self) -> DataFormat

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DataFormat

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DataFormat

fn default() -> Self

Returns the “default value” for a type.

impl Display for DataFormat

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<DataFormat> for char

fn from(f: DataFormat) -> char

Converts to this type from the input type.

impl From<DataFormat> for u8

fn from(f: DataFormat) -> u8

Converts to this type from the input type.

impl From<char> for DataFormat

fn from(c: char) -> Self

Converts to this type from the input type.

impl From<u8> for DataFormat

fn from(u: u8) -> Self

Converts to this type from the input type.

impl Hash for DataFormat

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for DataFormat

fn cmp(&self, other: &DataFormat) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<DataFormat> for DataFormat

fn eq(&self, other: &DataFormat) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<DataFormat> for DataFormat

fn partial_cmp(&self, other: &DataFormat) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
