Struct Pattern 

pub struct Pattern {
    pub template: String,
    pub occurrences: usize,
    pub window_ms: u64,
    pub distinct_params: usize,
    pub span_duration_us_p50: Option<u64>,

}

Pattern details for a finding.

Fields

template: String

Normalized query or URL template shared by the matched spans.

occurrences: usize

Number of spans that matched this template within the window.

window_ms: u64

Time span, in milliseconds, covering all matched occurrences.

distinct_params: usize

Count of distinct parameter sets observed across occurrences.

span_duration_us_p50: Option<u64>

Median per-span duration in the group (µs). Diagnostic field populated by the n+1 and slow detectors. Not used in the detection verdict, exposed so downstream consumers can profile cache-warm patterns without needing daemon-log access.

span_duration_us_p99: Option<u64>

99th-percentile per-span duration in the group (µs).

span_duration_cv_x1000: Option<u32>

Coefficient of variation of per-span durations, scaled by 1000 (523 means CV = 0.523). Avoids floating-point fields so Pattern can keep its Eq derive.

Trait Implementations

impl Clone for Pattern

fn clone(&self) -> Pattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Pattern

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

Formats the value using the given formatter.

impl Default for Pattern

fn default() -> Pattern

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Pattern

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Pattern

impl PartialEq for Pattern

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
