Detailed Description

Shared, reference-counted state behind every metric handle.

It owns the stable string/buffer storage that MetricMeta views into, the adapter source it reads its backend from, the currently-published binding, and the bookkeeping for lazy/live binding and runtime unit reconciliation.

Member Function Documentation

◆ build_meta()

MetricMeta prom::MetricCore::build_meta ( ) const

inline

Assemble the transient registration metadata.

The returned views/spans are valid only while *this outlives the call (always true: the caller holds the core).

◆ unit_view()

Unit prom::MetricCore::unit_view ( ) const

inline

Build a non-owning view of the currently-known unit.
