//! Rust backend SDK for applications on the Fluence network. This crate defines the procedure macro
//! `#[marine]` that could be applied to a function, structure or extern block.
//!
//! Structures with `#[marine]` (hereinafter they'll be called records) could be used then in function
//! arguments and values. All fields of a record should be public and have one of the
//! following primitive Rust types
//! (`bool, u8, u16, u32, u64, i8, i16, i32, i64, f32, f64, String, Vec<u8>`).
//! ```rust
//! use marine_rs_sdk::marine;
//!
//! #[marine]
//! struct T {
//!     pub field_1: i32,
//!     pub field_2: Vec<u8>,
//! }
//! ```
//!
//! Functions with `#[marine]` will be exported from this module:
//!
//! ```rust
//! use marine_rs_sdk::marine;
//!
//! #[marine]
//! pub fn get(url: String) {
//!     // ...
//! }
//! ```
//! At now, such functions could have arguments with primitive Rust types and record and only one
//! return argument with such type could be used.
//!
//! Finally, to import other wasm modules to your project use similar code:
//! ```rust
//! use marine_rs_sdk::marine;
//!
//! #[marine]
//! #[link(wasm_import_module = "wasm_curl.wasm")]
//! extern "C" {
//!     #[link_name = "get"]
//!     pub fn curl_get(url: String) -> String;
//! }
//! ```
