Struct Note

pub struct Note {
    pub nonce: Nonce,
    pub signature: Signature,
}

An verifiable one time use IOU from the mint.

Digital version of a “note of deposit” in a free-banking era.

Consist of a user-generated nonce and a threshold signature over it generated by the federated mint (while in a BlindNonce form).

As things are right now the denomination of each note is determined by the federation keys that signed over it, and needs to be tracked outside of this type.

In this form it can only be validated, not spent since for that the corresponding secret spend key is required.

Fields

nonce: Nonce

signature: Signature

Implementations

impl Note

pub fn verify(&self, pk: AggregatePublicKey) -> bool

Trait Implementations

impl Clone for Note

fn clone(&self) -> Note

Returns a copy of the value.

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

Formats the value using the given formatter.

impl Decodable for Note

fn consensus_decode_from_finite_reader<D>( d: &mut D, modules: &ModuleRegistry<Decoder, DecodingMode>, ) -> Result<Note, DecodeError>

where D: Read,

Decode Self from a size-limited reader.

fn consensus_decode_whole( slice: &[u8], modules: &ModuleRegistry<Decoder, DecodingMode>, ) -> Result<Self, DecodeError>

fn consensus_decode<R>( r: &mut R, modules: &ModuleRegistry<Decoder, DecodingMode>, ) -> Result<Self, DecodeError>

where R: Read,

Decode an object with a well-defined format.

fn consensus_decode_hex( hex: &str, modules: &ModuleRegistry<Decoder, DecodingMode>, ) -> Result<Self, DecodeError>

Decode an object from hex

fn consensus_decode_vec( bytes: Vec<u8>, modules: &ModuleRegistry<Decoder, DecodingMode>, ) -> Result<Self, DecodeError>

impl<'de> Deserialize<'de> for Note

fn deserialize<__D>( __deserializer: __D, ) -> Result<Note, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Note

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

Formats the value using the given formatter.

impl Encodable for Note

fn consensus_encode<W>(&self, writer: &mut W) -> Result<usize, Error>

where W: Write,

Encode an object with a well-defined format. Returns the number of bytes written on success.

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

Self::consensus_encode to newly allocated Vec<u8>

fn consensus_encode_to_hex(&self) -> String

Encode and convert to hex string representation

fn consensus_encode_to_len(&self) -> usize

Encode without storing the encoding, return the size

fn consensus_hash<H>(&self) -> H

where H: Hash, <H as Hash>::Engine: Write,

Generate a SHA256 hash of the consensus encoding using the default hash engine for H.

impl PartialEq for Note

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
