WebAssembly Sources

The WASM (WebAssembly) source is used for blueprints that are built as WASM binaries and intended to be executed in a WASM runtime such as Wasmtime.

Requirements

The requirements for running WASM blueprints are available here

Format

The WASM source has the following format:

pub struct WasmSource {
    pub runtime: WasmRuntime,
    pub fetcher: NativeSource,
}

Where:

• runtime - The WASM runtime this blueprint is intended to execute in (see WasmRuntime)
• fetcher - The GitHub release information, identical to NativeSource

And they can be specified in the manifest of your binary crate like so:

[package.metadata.blueprint]
sources = [
    { type = "Wasm", runtime = "Wasmtime", fetcher = { owner = "some-github-user", repo = "some-blueprint", tag = "0.1.0", binaries = [
        { arch = "Wasm", os = "Unknown", name = "my-blueprint-bin" },
    ] } },
]
