Crate metricus 

metricus

Contains building blocks.

Structs

Counter

Provides methods to create a new counter, increment it, and increment it by a specified amount. It automatically deletes the counter when it is dropped.

Histogram

Facilitates the creation of a new histogram, recording of values, and generation of spans for timing operations. The Histogram does not have an inherent notion of measurement units (e.g., milliseconds, bytes) and some convention should be in place.

MetricsHandle

Metrics backend handle.

Span

Used for measuring how long given operation takes. The duration is recorded in nanoseconds.

Enums

PreAllocatedMetric

Pre-allocated metric consists of name, id and tags.

Traits

CounterOps

Defines a series of operations that can be performed on a Counter.

HistogramOps

Metrics

Common interface for metrics backend. Each new backend must implement this trait.

Functions

empty_tags

Returns empty tags.

get_metrics_backend_name
