Struct FieldObservationEntry 

pub struct FieldObservationEntry {
    pub field: Arc<str>,
    pub count: u64,
}

Single field-name counter as exposed via the snapshot API.

The field name is held as Arc<str> so snapshotting only bumps a refcount rather than copying every key out of the observer’s internal map. Treat as a string slice for read access: entry.field.as_ref() or &*entry.field.

Fields

field: Arc<str>

Dot-joined field path (matches what Event::field_keys returns).

count: u64

Number of events that contained this field since the last reset.

Trait Implementations

impl Clone for FieldObservationEntry

fn clone(&self) -> FieldObservationEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldObservationEntry

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

Formats the value using the given formatter.

impl PartialEq for FieldObservationEntry

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