//! # Metric Semantic Conventions
//!
//! The [metric semantic conventions] define a set of standardized attributes to
//! be used in `Meter`s.
//!
//! [metric semantic conventions]: https://opentelemetry.io/docs/specs/semconv/general/metrics/
//!
//! ## Usage
//!
//! ```rust
//! use opentelemetry::{global, KeyValue};
//! use opentelemetry_semantic_conventions as semconv;
//!
//! // Assumes we already have an initialized `MeterProvider`
//! // See: https://github.com/open-telemetry/opentelemetry-rust/blob/main/examples/metrics-basic/src/main.rs
//! // for an example
//! let meter = global::meter("mylibraryname");
//! let histogram = meter
//!     .u64_histogram(semconv::metric::HTTP_SERVER_REQUEST_DURATION)
//!     .with_unit("s")
//!     .with_description("Duration of HTTP server requests.")
//!     .build();
//! ```
