Trait Implementations

impl<T: BorshSerialize + BorshDeserialize + Default + PartialEq> BorshDeserialize for NullableNumber<T>

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<T: BorshSerialize + BorshDeserialize + Default + PartialEq> BorshSerialize for NullableNumber<T>

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<T: Clone + BorshSerialize + BorshDeserialize + Default + PartialEq> Clone for NullableNumber<T>

fn clone(&self) -> NullableNumber<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + BorshSerialize + BorshDeserialize + Default + PartialEq> Debug for NullableNumber<T>

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

Formats the value using the given formatter.

impl Display for NullableNumber<u64>

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

Formats the value using the given formatter.

impl<T: PartialEq + BorshSerialize + BorshDeserialize + Default + PartialEq> PartialEq for NullableNumber<T>

fn eq(&self, other: &NullableNumber<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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