// A MeterProvider is the collection destination of all measurements made from

// on its implementation. Instrumentation authors do not need to define this
// implementation, rather just use the provided Meters to instrument code.

// https://pkg.go.dev/go.opentelemetry.io/otel/metric/global#MeterProvider).

//
// The passed name needs to uniquely identify instrumentation code.
// Therefore, it is recommended that name is the Go package name of the
// library providing instrumentation (note: not the code being
// instrumented). Instrumentation libraries can have multiple versions,
// therefore, the WithInstrumentationVersion option should be used to
// distinguish these different codebases. Additionally, instrumentation
// libraries may sometimes use metric measurements to communicate different
// domains of code operations data (i.e. using different Meters to
// communicate user experience and back-end operations). If this is the
// case, the WithScopeAttributes option should be used to uniquely identify
// Meters that handle the different domains of code operations data.
//
// If the same name and options are passed multiple times, the same Meter
// will be returned (it is up to the implementation if this will be the
// same underlying instance of that Meter or not). It is not necessary to
// call this multiple times with the same name and options to get an
// up-to-date Meter. All implementations will ensure any MeterProvider
// configuration changes are propagated to all provided Meters.
