Struct SnapshotObjectPrefix 

pub struct SnapshotObjectPrefix {
    pub audience: Audience,
    pub key: KeyId,
    pub covers: u64,
    pub purpose: Purpose,
}

Clear snapshot routing. Verify the prefix signature before using coverage.

Fields

audience: Audience

The audience of its rows and header.

key: KeyId

The audience key sealing section zero.

covers: u64

Last included slot, including consumed refusals.

purpose: Purpose

Ordinary snapshot or prepared admin state.

Implementations

impl SnapshotObjectPrefix

pub const MAX_SIGNED_PREFIX: usize

Greatest signed prefix end, including a circle and raised version.

pub fn signed_length(bytes: &[u8]) -> Result<usize, Error>

Bytes through the prefix signature.

pub fn plaintext_length(&self, object_length: u64) -> Result<u64, Error>

Plaintext size from the complete encrypted object size.

pub fn encode(&self) -> Result<Vec<u8>, Error>

Encode kind, format, routing, coverage and purpose.

pub fn length(bytes: &[u8]) -> Result<usize, Error>

Determine the bounded prefix length without allocation.

pub fn decode_signed(bytes: &[u8]) -> Result<(Self, Signature), Error>

Decode exactly the prefix and its signature, without authenticating them.

pub fn decode(bytes: &[u8]) -> Result<Self, Error>

Decode exactly the clear prefix.

Trait Implementations

impl Clone for SnapshotObjectPrefix

fn clone(&self) -> SnapshotObjectPrefix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SnapshotObjectPrefix

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

Formats the value using the given formatter.

impl PartialEq for SnapshotObjectPrefix

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

Tests for self and other values to be equal, and is used by ==.

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

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