Enum DynamicLabelStrategy 

pub enum DynamicLabelStrategy {
    ValuesList {
        values: Vec<String>,
    },
    Counter {
        prefix: Option<String>,
        cardinality: u64,
    },
}

Strategy for generating dynamic label values.

Determines how a DynamicLabelConfig produces per-tick values for the label key.

Variants

ValuesList

Cycle through an explicit list of values.

The label value at each tick is values[tick % values.len()]. Cardinality is implicit (length of the list).

Fields

values: Vec<String>

The explicit list of label values to cycle through.

Counter

Sequential counter: "{prefix}{tick % cardinality}".

Produces deterministic, predictable label values that cycle through cardinality distinct values indefinitely.

Fields

prefix: Option<String>

Prefix prepended to the counter index (e.g. "host-" produces "host-0", "host-1", …).

cardinality: u64

Number of unique label values in the cycle. Must be greater than zero.

Trait Implementations

impl Clone for DynamicLabelStrategy

fn clone(&self) -> DynamicLabelStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DynamicLabelStrategy

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DynamicLabelStrategy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DynamicLabelStrategy

fn eq(&self, other: &DynamicLabelStrategy) -> 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 DynamicLabelStrategy

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for DynamicLabelStrategy
