Enum NoteUpdateType 

#[repr(u8)]
pub enum NoteUpdateType {
    None = 0,
    Insert = 1,
    Update = 2,
    InsertCommitted = 3,
}

Represents the possible types of updates that can be applied to a note in a NoteUpdateTracker.

Variants

None = 0

Indicates that the note was already tracked but it was not updated.

Insert = 1

Indicates that the note is new and should be inserted in the store.

Update = 2

Indicates that the note was already tracked and should be updated.

InsertCommitted = 3

Indicates that a previously-tracked metadata-less (Expected) note has just been committed. It must be persisted as a full-row insert (like Self::Insert) so its now-known note_id and nullifier columns are written, but for reporting it is a committed tracked note — not a newly-discovered one — so it is summarized under committed notes, not new notes.

Implementations

impl NoteUpdateType

pub fn is_modified(self) -> bool

Whether this update carries a pending store write, as opposed to a note that was merely loaded as already-tracked context (Self::None). True for Self::Insert, Self::Update, and Self::InsertCommitted.

Trait Implementations

impl Clone for NoteUpdateType

fn clone(&self) -> NoteUpdateType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NoteUpdateType

impl Debug for NoteUpdateType

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

Formats the value using the given formatter.

impl Deserializable for NoteUpdateType

fn read_from<R: ByteReader>( source: &mut R, ) -> Result<Self, DeserializationError>

Reads a sequence of bytes from the provided source, attempts to deserialize these bytes into Self, and returns the result.

fn min_serialized_size() -> usize

Returns the minimum serialized size for one instance of this type.

fn read_from_bytes(bytes: &[u8]) -> Result<Self, DeserializationError>

Attempts to deserialize the provided bytes into Self and returns the result.

fn read_from_bytes_with_budget( bytes: &[u8], budget: usize, ) -> Result<Self, DeserializationError>

Deserializes Self from bytes with a byte budget limit.

impl Eq for NoteUpdateType

impl PartialEq for NoteUpdateType

fn eq(&self, other: &NoteUpdateType) -> 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 Serializable for NoteUpdateType

fn write_into<W: ByteWriter>(&self, target: &mut W)

Serializes self into bytes and writes these bytes into the target.

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

Serializes self into a vector of bytes.

fn get_size_hint(&self) -> usize

Returns an estimate of how many bytes are needed to represent self.

impl StructuralPartialEq for NoteUpdateType

impl TryFrom<u8> for NoteUpdateType

type Error = u8

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<Self, Self::Error>

Performs the conversion.
