Struct FieldProfile 

pub struct FieldProfile {
    pub field: String,
    pub present: u64,
    pub total: u64,
    pub distinct_values: Vec<String>,
    pub value_overflow: bool,
}

Per-field statistics gathered over a set of events in scope (a cluster or a whole corpus). A small standalone type so other corpus-analysis features can build on the same profile rather than duplicating the aggregation.

Fields

field: String

Dot-joined field path.

present: u64

Events in scope that contained the field.

total: u64

Total events in scope.

distinct_values: Vec<String>

Distinct string values seen, sorted, capped for memory. Empty when values were not retained (the online path) or the field is not string-valued.

value_overflow: bool

True when more distinct values were seen than retained, or a value was dropped as too long/sensitive to retain, so distinct_values is not the full set and the field is not a safe value marker.

Implementations

impl FieldProfile

pub fn prevalence(&self) -> f64

Fraction of in-scope events that contained the field (0.0-1.0).

pub fn cardinality(&self) -> usize

Number of distinct retained string values.
