Trait Implementations

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.

impl<'frame, 'metadata> DeserializeValue<'frame, 'metadata> for Counter

fn type_check(typ: &ColumnType<'_>) -> Result<(), TypeCheckError>

Checks that the column type matches what this type expects.

fn deserialize( typ: &'metadata ColumnType<'metadata>, v: Option<FrameSlice<'frame>>, ) -> Result<Self, DeserializationError>

Deserialize a column value from given serialized representation.

impl FromCqlVal<CqlValue> for Counter

fn from_cql(cql_val: CqlValue) -> Result<Counter, FromCqlValError>

👎Deprecated since 0.15.0: Legacy deserialization API is inefficient and is going to be removed soon

impl Ord for Counter

fn cmp(&self, other: &Counter) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Counter

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

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

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

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

impl PartialOrd for Counter

fn partial_cmp(&self, other: &Counter) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl SerializeValue for Counter

fn serialize<'b>( &self, typ: &ColumnType<'_>, writer: CellWriter<'b>, ) -> Result<WrittenCellProof<'b>, SerializationError>

Serializes the value to given CQL type.

impl Value for Counter

fn serialize(&self, buf: &mut Vec<u8>) -> Result<(), ValueTooBig>

👎Deprecated since 0.15.1: Legacy serialization API is not type-safe and is going to be removed soon

impl Copy for Counter

impl Eq for Counter

impl StructuralPartialEq for Counter
