Struct NoteMetadataHeader 

pub struct NoteMetadataHeader {
    pub sender: Option<AccountId>,
    pub note_type: i32,
    pub tag: u32,
    pub attachment_kind: i32,
    pub attachment_scheme: u32,
}

Represents the header of a note’s metadata.

Contains the sender, note type, tag and attachment type information, but not the full attachment data. See miden_protocol::note::NoteMetadataHeader for more info.

Fields

sender: Option<AccountId>

The account which sent the note.

note_type: i32

The type of the note.

tag: u32

A value which can be used by the recipient to identify notes intended for them.

See miden_protocol::note::note_tag for more info.

attachment_kind: i32

The kind of the note attachment.

attachment_scheme: u32

The scheme identifier of the note attachment.

Implementations

impl NoteMetadataHeader

pub fn note_type(&self) -> NoteType

Returns the enum value of note_type, or the default if the field is set to an invalid enum value.

pub fn set_note_type(&mut self, value: NoteType)

Sets note_type to the provided enum value.

pub fn attachment_kind(&self) -> NoteAttachmentKind

Returns the enum value of attachment_kind, or the default if the field is set to an invalid enum value.

pub fn set_attachment_kind(&mut self, value: NoteAttachmentKind)

Sets attachment_kind to the provided enum value.

Trait Implementations

impl Clone for NoteMetadataHeader

fn clone(&self) -> NoteMetadataHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NoteMetadataHeader

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

Formats the value using the given formatter.

impl Default for NoteMetadataHeader

fn default() -> Self

Returns the “default value” for a type.

impl From<NoteMetadataHeader> for NoteMetadataHeader

fn from(header: NoteMetadataHeader) -> Self

Converts to this type from the input type.

impl Hash for NoteMetadataHeader

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Message for NoteMetadataHeader

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

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

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

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

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for NoteMetadataHeader

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