Module manifest

The module_manifest! macro embeds the Interface Type, SDK, and Rust project version as well as additional project and build information into a Wasm module. For the macro to be usable, it needs to be imported and initialized:

rust
use marine_rs_sdk::marine;
use marine_rs_sdk::module_manifest;    // import manifest macro
module_manifest!(
  "Fluence Labs",                                // authors
  "0.1.0",                                       // version
  "The greeting module for the Fluence network", // description
  ".../marine/examples/greeting",                // repository
);
fn main() {}
#[marine]
fn greeting(name: &str) {...}

rust
use marine_rs_sdk::marine;
use marine_rs_sdk::module_manifest;    // import manifest macro
module_manifest!(
  "Fluence Labs",                                // authors
  "0.1.0",                                       // version
  "The greeting module for the Fluence network", // description
  ".../marine/examples/greeting",                // repository
);
fn main() {}
#[marine]
fn greeting(name: &str) {...}

Using the Marine CLI, we can inspect a module's manifest with marine info:

sh
marine info artifacts/greeting.wasm

sh
marine info artifacts/greeting.wasm

It's possible to omit arguments in the module_manifest, in this case it'll get them from Cargo.toml:

rust
use marine_rs_sdk::marine;
use marine_rs_sdk::module_manifest;    // import manifest macro
module_manifest!(st);
fn main() {}
#[marine]
fn greeting(name: &str) {...}

rust
use marine_rs_sdk::marine;
use marine_rs_sdk::module_manifest;    // import manifest macro
module_manifest!(st);
fn main() {}
#[marine]
fn greeting(name: &str) {...}
