Trait Implementations

impl Clone for ResettingNullableTotal

fn clone(&self) -> ResettingNullableTotal

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ResettingNullableTotal

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

Formats the value using the given formatter.

impl Default for ResettingNullableTotal

fn default() -> ResettingNullableTotal

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ResettingNullableTotal

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Option<u64>> for ResettingNullableTotal

fn from(f: Option<u64>) -> Self

Converts to this type from the input type.

impl PartialEq for ResettingNullableTotal

fn eq(&self, other: &ResettingNullableTotal) -> 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.

impl Serialize for ResettingNullableTotal

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StorageMetric for ResettingNullableTotal

fn summarize<'a, I>(values: I) -> Self

where I: IntoIterator<Item = &'a Self>, Self: Sized + 'a,

Summarizes a set of measurements into a single representative value. Typically this function is used to summarize the measurements collected from each worker.

fn incorporate(&mut self, other: Self, _field_name: &'static str)

Incorporate this value with another.
