provide-telemetry ships a Rust crate in this repo under rust/.

Features

• Default build: fallback telemetry primitives, context guards, schema enforcement, and in-process metrics.
• otel: enables OpenTelemetry dependencies used by the Rust E2E/OpenObserve paths.

Install locally from the repo:

cargo build --manifest-path rust/Cargo.toml
cargo build --manifest-path rust/Cargo.toml --features otel

• cargo run --manifest-path rust/Cargo.toml --features otel --example openobserve_03_hardening_profile
• cargo run --manifest-path rust/Cargo.toml --features otel --example e2e_cross_language_client
• cargo run --manifest-path rust/Cargo.toml --features otel --example e2e_cross_language_server -- --port 18765

The Rust example suite now covers the same numbered telemetry examples as Python and TypeScript, includes Rust OpenObserve examples, and keeps the OTLP E2E client/server pair used by the cross-language verification flow.
