Struct sn_dbc::SignedSpend

pub struct SignedSpend {
    pub spend: Spend,
    pub derived_key_sig: Signature,
}

SignedSpend’s are constructed when a DBC is logged to the spentbook.

Fields

spend: Spend

The Spend, which together with signature over it, constitutes the SignedSpend.

derived_key_sig: Signature

The DerivedKey’s signature over (the hash of) Spend, confirming that the Dbc was intended to be spent.

Implementations

impl SignedSpend

pub fn dbc_id(&self) -> &DbcId

Get public key of input Dbc.

pub fn spent_tx_hash(&self) -> Hash

Get the hash of the transaction this DBC is spent in

pub fn spent_tx(&self) -> DbcTransaction

Get the transaction this DBC is spent in

pub fn dbc_creation_tx_hash(&self) -> Hash

Get the hash of the transaction this DBC was created in

pub fn token(&self) -> &Token

Get Token

pub fn reason(&self) -> Hash

Get reason.

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

Represent this SignedSpend as bytes.

pub fn verify(&self, spent_tx_hash: Hash) -> Result<()>

Verify this SignedSpend

Checks that the provided spent_tx_hash equals the input dst tx hash that was signed by the DerivedKey. Also verifies that that signature is valid for this SignedSpend.

Trait Implementations

impl Clone for SignedSpend

fn clone(&self) -> SignedSpend

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SignedSpend

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

Formats the value using the given formatter.

impl Hash for SignedSpend

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 Ord for SignedSpend

fn cmp(&self, other: &SignedSpend) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<SignedSpend> for SignedSpend

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<SignedSpend> for SignedSpend

fn partial_cmp(&self, other: &SignedSpend) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
