Struct SlotObjectPrefix 

pub struct SlotObjectPrefix {
    pub format: FormatVersion,
    pub key: KeyId,
    pub kind: SlotKind,
}

The complete clear routing, without any device, claim number or part audience.

Fields

format: FormatVersion

The recorded format of this claim attempt.

key: KeyId

The store key sealing the body.

kind: SlotKind

Kind and any key boxes.

Implementations

impl SlotObjectPrefix

pub const MAX_LENGTH: usize

Longest prefix of any slot but an admission, including a circle key copy. An admission’s prefix is bounded only by its slot’s 4 MiB.

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

Encode the exact associated-data prefix, including any anonymous box.

pub fn copy_context( format: FormatVersion, key: KeyId, place: BoxPlace, routing: &KeyCopyPrefix, ) -> Result<Vec<u8>, Error>

Box context through the recipient’s sealing key, before generating its ephemeral key and ciphertext: the slot’s fixed fields, the box’s place and its routing. This context binds the slot path in crypto.

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

Whether the prefix bytes begins is an admission’s, whose length only its whole bounded slot bounds. It reads the first four bytes.

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

Bound the clear prefix before reading its boxes. No length supplied by a peer can enlarge the fixed store/circle box sizes.

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

Decode exactly the prefix, without authenticating routing.

pub fn fits(&self, plaintext: usize) -> Result<bool, Error>

Whether the complete bounded slot with this prefix and plaintext bytes of frames stays within its 4-MiB limit, signature included (D2). An operation checks it before it claims anything.

pub fn encode_chunk(&self, chunk: &[u8]) -> Result<Vec<u8>, Error>

Frame the sole sealed chunk of an admin, admission, copy or announcement slot. Checks the complete 4-MiB limit including the eventual signature.

Trait Implementations

impl Clone for SlotObjectPrefix

fn clone(&self) -> SlotObjectPrefix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SlotObjectPrefix

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

Formats the value using the given formatter.

impl PartialEq for SlotObjectPrefix

fn eq(&self, other: &SlotObjectPrefix) -> 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.
