server-less-core

Runtime support crate for server-less — the foundational traits and types that the derive macros generate against.

Most users don't depend on this directly. It's pulled in transitively when you depend on the server-less facade. Reach for it directly only when you're writing code that interoperates with generated output at the trait level.

What's inside

• Error model — ErrorCode and the IntoErrorCode trait, plus ErrorResponse, HttpStatusHelper, and HttpStatusFallback. These back #[derive(ServerlessError)] and give every protocol projection a consistent way to map errors to HTTP statuses, exit codes, gRPC codes, and JSON-RPC codes.
• Context extraction — the Context extractor (and WsSender for WebSocket) used to pass request-scoped state into your methods.
• CLI manual & output — CliManualNode and the cli_manual_to_json / cli_manual_to_text helpers that build the whole-tree --manual reference surface, plus cli_format_output for --json / --jq formatting.
• Mount & dispatch traits — CliSubcommand, McpNamespace, JsonRpcMount, WsMount, and HttpMount for composing nested subcommands and routers.
• Inference primitives — MethodInfo, ParamInfo, HttpMethod, and path inference shared across projections.
• Config module — runtime support for #[derive(Config)] (TOML + environment layering).

Features

These mirror the corresponding features on the server-less facade and are normally selected for you by it.
