Release Notes

prometheus/client_rust (prometheus-client)

v0.26.0

Compare Source

Added

• Implement PartialEq, Eq and Hash for metrics::MetricType and registry::Unit. See PR 366.
• Added encoding::prometheus_text::encode to encode a Registry in the Prometheus text exposition format (version 0.0.4). See Issue 367 and PR 368.

Changed

• Improved text encoding performance by buffering output internally, reducing
  dynamic dispatch overhead. Empty label sets and custom labels that encode no
  key no longer produce {} or a stray , in the text output. See PR 370.
• Registering a Counter with a name ending in _total now panics when debug
  assertions are enabled, including default development and test builds. When
  upgrading, remove the suffix from registered names (for example, foo_total ->
  foo); encoding adds it automatically. In this example, the exported name
  changes from foo_total_total to foo_total, so update affected queries and
  dashboards. The new check is disabled in builds without debug assertions,
  including default release builds. See PR 371.
