//! Rust backend SDK for applications on the Fluence network. This crate defines the procedure macro
|
|
//! `#[fce]` that could be applied to a function, structure or extern block.
|
|
//!
|
|
//! Structures with `#[fce]` (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 fluence::fce;
|
|
//!
|
|
//! #[fce]
|
|
//! struct T {
|
|
//! pub field_1: i32,
|
|
//! pub field_2: Vec<u8>,
|
|
//! }
|
|
//! ```
|
|
//!
|
|
//! Functions with `#[fce]` will be exported from this module:
|
|
//!
|
|
//! ```rust
|
|
//! use fluence::fce;
|
|
//!
|
|
//! #[fce]
|
|
//! 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 fluence::fce;
|
|
//!
|
|
//! #[fce]
|
|
//! #[link(wasm_import_module = "wasm_curl.wasm")]
|
|
//! extern "C" {
|
|
//! #[link_name = "get"]
|
|
//! pub fn curl_get(url: String) -> String;
|
|
//! }
|
|
//! ```
