Struct sequoia_openpgp::packet::prelude::MDC

pub struct MDC { /* private fields */ }

Holds an MDC packet.

A modification detection code packet. This packet appears after a SEIP packet. See Section 5.14 of RFC 4880 for details.

A note on equality

Two MDC packets are considered equal if their serialized form is equal. This excludes the computed digest.

Implementations

impl MDC

pub fn new(digest: [u8; 20], computed_digest: [u8; 20]) -> Self

Creates an MDC packet.

pub fn digest(&self) -> &[u8]

Gets the packet’s hash value.

pub fn computed_digest(&self) -> &[u8]

Gets the computed hash value.

pub fn valid(&self) -> bool

Returns whether the data protected by the MDC is valid.

Trait Implementations

impl Any<MDC> for Packet

fn downcast(self) -> Result<MDC, Packet>

Attempts to downcast to T, returning the packet if it fails.

fn downcast_ref(&self) -> Option<&MDC>

Attempts to downcast to &T, returning None if it fails.

fn downcast_mut(&mut self) -> Option<&mut MDC>

Attempts to downcast to &mut T, returning None if it fails.

impl Clone for MDC

fn clone(&self) -> MDC

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MDC

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

Formats the value using the given formatter.

impl From<[u8; 20]> for MDC

fn from(digest: [u8; 20]) -> Self

Converts to this type from the input type.

impl From<Box<dyn Digest + 'static, Global>> for MDC

fn from(hash: Box<dyn Digest>) -> Self

Converts to this type from the input type.

impl From<MDC> for Packet

fn from(s: MDC) -> Self

Converts to this type from the input type.

impl Hash for MDC

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, 

Feeds a slice of this type into the given Hasher.

impl IntoIterator for MDC

Implement IntoIterator so that cert::insert_packets(sig) just works.

type Item = MDC

The type of the elements being iterated over.

type IntoIter = Once<MDC>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl Marshal for MDC

fn serialize(&self, o: &mut dyn Write) -> Result<()>

Writes a serialized version of the object to o.

fn export(&self, o: &mut dyn Write) -> Result<()>

Exports a serialized version of the object to o.

impl MarshalInto for MDC

fn serialized_len(&self) -> usize

Computes the maximal length of the serialized representation.

fn serialize_into(&self, buf: &mut [u8]) -> Result<usize>

Serializes into the given buffer.

fn to_vec(&self) -> Result<Vec<u8>>

Serializes the packet to a vector.

fn export_into(&self, buf: &mut [u8]) -> Result<usize>

Exports into the given buffer.

fn export_to_vec(&self) -> Result<Vec<u8>>

Exports to a vector.

impl<'a> Parse<'a, MDC> for MDC

fn from_reader<R: 'a + Read + Send + Sync>(reader: R) -> Result<Self>

Reads from the given reader.

fn from_bytes<D: AsRef<[u8]> + ?Sized + Send + Sync>(
    data: &'a D
) -> Result<Self>

Reads from the given slice.

fn from_file<P: AsRef<Path>>(path: P) -> Result<T>

Reads from the given file.

impl PartialEq<MDC> for MDC

fn eq(&self, other: &MDC) -> 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 !=.
