Enum vector::event::MetricKind

pub enum MetricKind {
    Incremental,
    Absolute,
}

Metric kind.

Metrics can be either absolute or incremental. Absolute metrics represent a sort of “last write wins” scenario, where the latest absolute value seen is meant to be the actual metric value. In contrast, and perhaps intuitively, incremental metrics are meant to be additive, such that we don’t know what total value of the metric is, but we know that we’ll be adding or subtracting the given value from it.

Generally speaking, most metrics storage systems deal with incremental updates. A notable exception is Prometheus, which deals with, and expects, absolute values from clients.

Trait Implementations

impl Clone for MetricKind

fn clone(&self) -> MetricKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Configurable for MetricKind

Gets the referenceable name of this value, if any.

fn metadata() -> Metadata

Gets the metadata for this value.

fn generate_schema( schema_gen: &RefCell<SchemaGenerator>, ) -> Result<SchemaObject, GenerateError>

Generates the schema for this value.

fn is_optional() -> bool

where Self: Sized,

Whether or not this value is optional.

fn validate_metadata(_metadata: &Metadata) -> Result<(), GenerateError>

where Self: Sized,

Validates the given metadata against this type.

fn as_configurable_ref() -> ConfigurableRef

where Self: Sized + 'static,

Create a new configurable reference table.

impl Debug for MetricKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MetricKind

fn deserialize<__D>( __deserializer: __D, ) -> Result<MetricKind, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<MetricKind> for Value

fn from(kind: MetricKind) -> Value

Converts to this type from the input type.

impl FromLua for MetricKind

fn from_lua(value: Value, _: &Lua) -> Result<MetricKind, Error>

Performs the conversion.

impl Hash for MetricKind

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

impl IntoLua for MetricKind

fn into_lua(self, lua: &Lua) -> Result<Value, Error>

Performs the conversion.

impl PartialEq for MetricKind

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

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.

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToValue for MetricKind

fn to_value(&self) -> Value

Convert this value into a serde_json::Value. Must not fail.

impl TryFrom<Value> for MetricKind

type Error = String

The type returned in the event of a conversion error.

fn try_from( value: Value, ) -> Result<MetricKind, <MetricKind as TryFrom<Value>>::Error>
