Metadata associated with a tangle message.

Implementations

impl MessageMetadata

pub fn arrival_timestamp(&self) -> u64

Get the arrival timestamp (seconds from the unix epoch) of this message.

pub fn solidification_timestamp(&self) -> u64

Get the solidification timestamp (seconds from the unix epoch) of this message.

pub fn omrsi(&self) -> Option<IndexId>

Get the oldest message root snapshot index of this message.

pub fn set_omrsi(&mut self, omrsi: IndexId)

Set the oldest message root snapshot index of this message.

pub fn ymrsi(&self) -> Option<IndexId>

Get the youngest message root snapshot index of this message.

pub fn set_ymrsi(&mut self, ymrsi: IndexId)

Set the youngest message root snapshot index of this message.

pub fn reference_timestamp(&self) -> u64

Get the reference timestamp (seconds from the unix epoch) of this message.

pub fn mark_solid(&mut self)

Mark this message as solid at the current system time.

pub fn reference(&mut self, timestamp: u64)

pub fn conflict(&self) -> ConflictReason

Get the conflict state of this message.

pub fn set_conflict(&mut self, conflict: ConflictReason)

Set the conflict state of this message.

Trait Implementations

impl Clone for MessageMetadata

fn clone(&self) -> MessageMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageMetadata

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

Formats the value using the given formatter.

impl Default for MessageMetadata

fn default() -> MessageMetadata

Returns the “default value” for a type.

impl Packable for MessageMetadata

type Error = MessageMetadataError

Associated error type.

fn packed_len(&self) -> usize

Returns the length of the packed bytes.

fn pack<W: Write>(&self, writer: &mut W) -> Result<(), Self::Error>

Packs the instance to bytes and writes them to the passed writer.

fn unpack_inner<R: Read + ?Sized, const CHECK: bool>( reader: &mut R, ) -> Result<Self, Self::Error>

Reads bytes from the passed reader and unpacks them into an instance.

fn pack_new(&self) -> Vec<u8>

Packs the instance to bytes and writes them to a newly allocated vector.

fn unpack<R>(reader: &mut R) -> Result<Self, Self::Error>

where R: Read + ?Sized, Self: Sized,

Reads bytes from the passed reader and unpacks them into an instance. Applies syntactic checks.

fn unpack_unchecked<R>(reader: &mut R) -> Result<Self, Self::Error>

where R: Read + ?Sized, Self: Sized,

Reads bytes from the passed reader and unpacks them into an instance. Doesn’t apply syntactic checks.

impl PartialEq for MessageMetadata

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

impl Serialize for MessageMetadata

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
