Struct SlotHeader 

pub struct SlotHeader {
    pub device: DeviceId,
    pub claim: u64,
    pub author: MemberId,
    pub after: u64,
}

The author and claim identity sealed under the store key in every slot.

Fields

device: DeviceId

The claiming device.

claim: u64

Positive number from this device’s counter across every slot kind.

author: MemberId

The member whose credential signs the slot.

after: u64

The immediately preceding slot, zero for creation.

Implementations

impl SlotHeader

pub const ENCODED_LEN: usize

The encoded frame’s length: its prefix, then device, claim, author and predecessor.

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

Encode the kind-14 frame, checking its path binding.

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

Decode exactly the kind-14 frame and check its path binding.

pub fn validate_at(&self, path: &ObjectPath) -> Result<(), Error>

A header’s predecessor must be exactly one less than its path’s slot.

pub fn check_write(&self, write: &WriteHeader) -> Result<(), Error>

Check an opened inner write against its containing slot. The consumer resolves its historical signer and its source writes separately.

Trait Implementations

impl Clone for SlotHeader

fn clone(&self) -> SlotHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SlotHeader

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

Formats the value using the given formatter.

impl PartialEq for SlotHeader

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