Crate spin_sdk 

The Rust Spin SDK.

This crate is the main entry point for building Spin components in Rust. Each capability is exposed as a feature-gated module. All features are enabled by default; disable default-features and pick only what you need to slim down compile times.

The http_service and redis_subscriber attribute macros generate the boilerplate required to expose a component to the Spin runtime.

Macros

dependencies

This macro generates code from a Spin components dependencies using wit-bindgen. During expansion the macro will check for existence of a spin-dependencies.wit in the developers project directory and if it is present (used to indicate the presence of dependencies in the manifest) will invoke wit-bindgen to generate the bindings.

Attribute Macros

http_service

Marks an async fn as an HTTP component entrypoint for Spin.

redis_subscriber

The entrypoint to a Spin Redis component.
