Trait Implementations

impl BorshDeserialize for ZkProof

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for ZkProof

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

impl Clone for ZkProof

fn clone(&self) -> ZkProof

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ZkProof

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

Formats the value using the given formatter.
