Trait Implementations

impl Clone for AmountSecrets

fn clone(&self) -> AmountSecrets

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AmountSecrets

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AmountSecrets

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

Deserialize this value from the given Serde deserializer.

impl From<u64> for AmountSecrets

fn from(amount: Amount) -> Self

create AmountSecrets from an amount and a randomly generated blinding factor

impl Hash for AmountSecrets

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, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<AmountSecrets> for AmountSecrets

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

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

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

This method tests for !=.

impl Serialize for AmountSecrets

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.

impl<I: IntoFr + Ord> TryFrom<(&'_ PublicKeySet, &'_ BTreeMap<I, DecryptionShare>, &'_ Ciphertext)> for AmountSecrets

fn try_from(
    params: (&PublicKeySet, &BTreeMap<I, DecryptionShare>, &Ciphertext)
) -> Result<Self, Error>

Decrypt AmountSecrets using threshold+1 DecryptionShares

This fn should be used when keys (SecretKeyShare) are distributed across multiple parties. In which case each party will need to call SecretKeyShare::decrypt_share() or decrypt_share_no_verify() to generate a DecryptionShare and one party will need to obtain/aggregate all the shares together somehow.

type Error = Error

The type returned in the event of a conversion error.

impl<I: IntoFr + Ord> TryFrom<(&'_ PublicKeySet, &'_ BTreeMap<I, SecretKeyShare>, &'_ Ciphertext)> for AmountSecrets

fn try_from(
    params: (&PublicKeySet, &BTreeMap<I, SecretKeyShare>, &Ciphertext)
) -> Result<Self, Error>

Decrypt AmountSecrets ciphertext using threshold+1 SecretKeyShares

type Error = Error

The type returned in the event of a conversion error.

impl TryFrom<(&'_ SecretKey, &'_ Ciphertext)> for AmountSecrets

fn try_from(params: (&SecretKey, &Ciphertext)) -> Result<Self, Error>

Decrypt AmountSecrets ciphertext using a SecretKey

type Error = Error

The type returned in the event of a conversion error.

impl TryFrom<(&'_ SecretKeySet, &'_ Ciphertext)> for AmountSecrets

fn try_from(params: (&SecretKeySet, &Ciphertext)) -> Result<Self, Error>

Decrypt AmountSecrets ciphertext using a SecretKeySet

type Error = Error

The type returned in the event of a conversion error.
