Expand description

OpenTelemetry provides a single set of APIs, libraries, agents, and collector services to capture distributed traces and metrics from your application. You can analyze them using Prometheus, Jaeger, and other observability tools.

Compiler support: requires rustc 1.49+

Supported Rust Versions

OpenTelemetry is built against the latest stable release. The minimum supported version is 1.49. The current OpenTelemetry version is not guaranteed to build on Rust versions earlier than the minimum supported version.

The current stable Rust compiler and the three most recent minor versions before it will always be supported. For example, if the current stable compiler version is 1.49, the minimum supported version will not be increased past 1.46, three minor versions prior. Increasing the minimum supported compiler version is not considered a semver breaking change as long as doing so complies with this policy.
