Enum MetricDetailLevel 

pub enum MetricDetailLevel {
    Process,
    Frontend,
    Cluster,
    Backend,
}

Cardinality knob for metrics labels in the StatsD network drain.

Mirrors HAProxy’s process|frontend|backend|server extra-counters opt-in. Operators choose the lowest level that satisfies their dashboards so that the keyspace stays bounded. Each level is a SUPERSET of the previous one:

• process — proxy-only counters (no listener, cluster, or backend label).
• frontend — adds per-listener (frontend) breakdown.
• cluster — adds per-cluster aggregation. Default (preserves the pre-knob behaviour).
• backend — adds per-backend aggregation (cluster + backend, highest cardinality).

Trait Implementations

impl Clone for MetricDetailLevel

fn clone(&self) -> MetricDetailLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetricDetailLevel

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

Formats the value using the given formatter.

impl Default for MetricDetailLevel

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MetricDetailLevel

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<MetricDetail> for MetricDetailLevel

fn from(detail: MetricDetail) -> Self

Reverse of [From<MetricDetailLevel> for MetricDetail] — used by the worker side to convert the protobuf wire enum back into the configuration enum before passing it to sozu_lib::metrics::setup.

impl From<MetricDetailLevel> for MetricDetail

fn from(level: MetricDetailLevel) -> Self

Converts to this type from the input type.

impl Hash for MetricDetailLevel

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for MetricDetailLevel

fn cmp(&self, other: &MetricDetailLevel) -> 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,

Restrict a value to a certain interval.

impl PartialEq for MetricDetailLevel

fn eq(&self, other: &MetricDetailLevel) -> 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 PartialOrd for MetricDetailLevel

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for MetricDetailLevel

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for MetricDetailLevel

impl Eq for MetricDetailLevel
