Struct Event

pub struct Event {
    pub time: SystemTime,
    pub metadata: &'static Metadata<'static>,
    pub seq: usize,
    /* private fields */
}

An event that has been recorded by a Recorder.

Fields

time: SystemTime

The time at which the event was recorded.

metadata: &'static Metadata<'static>

The metadata for the event.

seq: usize

A monotonically increasing sequence number.

Implementations

impl Event

pub fn json_value(&self) -> Value

The fields of this event, structed as a JSON value.

pub fn json_fields(&self) -> Map<String, Value>

The fields of this event, structured as a JSON map.

pub fn fields(&self) -> Vec<(String, Value)>

The fields of this event, using the Value representation.
