Struct sn_transfers::SignedSpend
source · pub struct SignedSpend {
pub spend: Spend,
pub derived_key_sig: Signature,
}
Expand description
Types used in the public API SignedSpend’s are constructed when a CashNote is logged to the spentbook.
Fields§
§spend: Spend
The Spend, which together with signature over it, constitutes the SignedSpend.
derived_key_sig: Signature
The DerivedSecretKey’s signature over (the hash of) Spend, confirming that the CashNote was intended to be spent.
Implementations§
source§impl SignedSpend
impl SignedSpend
sourcepub fn unique_pubkey(&self) -> &UniquePubkey
pub fn unique_pubkey(&self) -> &UniquePubkey
Get public key of input CashNote.
sourcepub fn address(&self) -> SpendAddress
pub fn address(&self) -> SpendAddress
Get the SpendAddress where this Spend shoud be
sourcepub fn spent_tx_hash(&self) -> Hash
pub fn spent_tx_hash(&self) -> Hash
Get the hash of the transaction this CashNote is spent in
sourcepub fn spent_tx(&self) -> Transaction
pub fn spent_tx(&self) -> Transaction
Get the transaction this CashNote is spent in
sourcepub fn parent_tx_hash(&self) -> Hash
pub fn parent_tx_hash(&self) -> Hash
Get the hash of the transaction this CashNote was created in
sourcepub fn token(&self) -> &NanoTokens
pub fn token(&self) -> &NanoTokens
Get Nano
sourcepub fn verify(&self, spent_tx_hash: Hash) -> Result<()>
pub fn verify(&self, spent_tx_hash: Hash) -> Result<()>
Verify a SignedSpend
Checks that
- the spend was indeed spent for the given Tx
- it was signed by the DerivedSecretKey that owns the CashNote for this Spend
- the signature is valid
- its value didn’t change between the two transactions it is involved in (creation and spending)
It does NOT check:
- if the spend exists on the Network
- the spend’s parents and if they exist on the Network
sourcepub fn verify_parent_spends<'a, T>(&self, parent_spends: T) -> Result<()>
pub fn verify_parent_spends<'a, T>(&self, parent_spends: T) -> Result<()>
Verify the parents of this Spend, making sure the input parent_spends are ancestors of self.
- verifies that the parent_spends where spent in our spend’s parent_tx
- verifies the parent_tx against the parent_spends
