//! Generated OpenTelemetry semantic-convention name constants for
//! RuView's curated telemetry (event names and attribute keys).
//!
//! GENERATED from `semconv/registry/` by `weaver registry generate`.
//! Do not edit by hand: change the registry or the template at
//! `templates/registry/rust/`, then regenerate (the exact command CI
//! runs — note `--future`, matching `weaver registry check --future`)
//! from the repository root and commit the result:
//!
//! ```text
//! weaver registry generate rust v2/crates/wifi-densepose-sensing-server/src \
//!     -t templates -r semconv/registry --future
//! cargo fmt -p wifi-densepose-sensing-server
//! ```
//!
//! The CI `semconv` workflow fails if this file drifts from the registry.
