Worked on the prometheus/docs repository to enhance documentation for Rust Prometheus users by adding explicit links to Rust metric types, including counter, gauge, and histogram, within the metric_types.md file. Focused on improving developer onboarding and usage accuracy, the changes were carefully scoped to a single Markdown file to minimize risk and ensure efficient delivery. The work centered on documentation skills and Markdown language proficiency, with no bug fixes addressed during this period. By providing precise cross-references, the update aimed to reduce onboarding time and promote correct usage of Rust client libraries, delivering direct business value through improved documentation clarity.
