Trait Implementations

impl BorshDeserialize for Counter

where Key: BorshDeserialize, Pubkey: BorshDeserialize, u32: BorshDeserialize,

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 Counter

where Key: BorshSerialize, Pubkey: BorshSerialize, u32: BorshSerialize,

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

fn try_to_vec(&self) -> Result<Vec<u8>, Error>

Serialize this instance into a vector of bytes.

impl Clone for Counter

fn clone(&self) -> Counter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Counter

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

Formats the value using the given formatter.
