Struct Frame

pub struct Frame {
    pub end_time: UnixTimestampMilliseconds,
    pub gauge_updates: HashMap<MetricId, f64>,
    pub counter_updates: HashMap<MetricId, Uint>,
    pub histograms: HashMap<MetricId, SerialisableHistogram>,
    pub new_metrics: HashMap<MetricId, MetricDescriptor>,
}

A single frame of metrics. Has an end timestamp (the start timestamp should be inferred from the previous frame or the header of the log file.

Fields

end_time: UnixTimestampMilliseconds

Unix timestamp (milliseconds) describing the end of this frame of metrics.

gauge_updates: HashMap<MetricId, f64>

Absolute values of updated gauges.

counter_updates: HashMap<MetricId, Uint>

Absolute values of updated counters. TODO should this be counts only for this window?

histograms: HashMap<MetricId, SerialisableHistogram>

Histograms only for this frame (this keeps them compact).

new_metrics: HashMap<MetricId, MetricDescriptor>

Descriptors of NEW metrics.

impl Debug for Frame

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

Formats the value using the given formatter.

impl Default for Frame

fn default() -> Frame

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Frame

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.
