Standard library

Protos keeps the language core and reusable library facilities conceptually separate. This website consumes the Standard Library from the same exact immutable Protos revision as the language reference, guide, tutorials, and examples.

API reference

Browse the Standard Library API for the complete D067 mechanically observable importable std: module/top-level-slot inventory.

The API pages are generated by the Protos-owned documentation producer from that same exact revision and rendered from the neutral D064 JSON model. Authored D062 //! / /// documentation is shown when present. Missing prose is shown explicitly rather than used to hide an observable module or slot.

Mechanical presence does not by itself imply support, stability, compatibility, deprecation, or any other API-lifecycle promise.

Exact source browser

Browse the Standard Library source to inspect every .protos module in the locked protos/lib tree, including physical core/** implementation sources that are deliberately not importable as std:core.

The source browser preserves canonical family names, filenames, case, relative paths, source bodies, and exact-SHA provenance. It remains implementation presentation, not an independent semantic authority.

For observable language semantics, use the Language reference.
