Struct InputNoteCommitment 

pub struct InputNoteCommitment { /* private fields */ }

The commitment to an input note.

For notes authenticated by the transaction kernel, the commitment consists only of the note’s nullifier. For notes whose authentication is delayed to batch/block kernels, the commitment also includes full note header (i.e., note ID and metadata).

Implementations

impl InputNoteCommitment

pub fn from_parts_unchecked( nullifier: Nullifier, header: Option<NoteHeader>, ) -> Self

Returns a new InputNoteCommitment instantiated from the provided nullifier and optional note header.

Note: this method does not validate that the provided nullifier and header are consistent with each other (i.e., it does not check that the nullifier was derived from the note referenced by the header).

pub fn nullifier(&self) -> Nullifier

Returns the nullifier of the input note committed to by this commitment.

pub fn header(&self) -> Option<&NoteHeader>

Returns the header of the input committed to by this commitment.

Note headers are present only for notes whose presence in the change has not yet been authenticated.

pub fn is_authenticated(&self) -> bool

Returns true if this commitment is for a note whose presence in the chain has been authenticated.

Authenticated notes are represented solely by their nullifiers and are missing the note header.

Trait Implementations

impl Clone for InputNoteCommitment

fn clone(&self) -> InputNoteCommitment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InputNoteCommitment

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

Formats the value using the given formatter.

impl Deserializable for InputNoteCommitment

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 From<&InputNote> for InputNoteCommitment

fn from(note: &InputNote) -> Self

Converts to this type from the input type.

impl From<InputNote> for InputNoteCommitment

fn from(note: InputNote) -> Self

Converts to this type from the input type.

impl From<Nullifier> for InputNoteCommitment

fn from(nullifier: Nullifier) -> Self

Converts to this type from the input type.

impl PartialEq for InputNoteCommitment

fn eq(&self, other: &InputNoteCommitment) -> 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 InputNoteCommitment

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.
