Crate marine_rs_sdk[][src]

Expand description

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>).

use marine_rs_sdk::marine;

struct T {
    pub field_1: i32,
    pub field_2: Vec<u8>,

Functions with #[marine] will be exported from this module:

use marine_rs_sdk::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:

use marine_rs_sdk::marine;

#[link(wasm_import_module = "wasm_curl.wasm")]
extern "C" {
    #[link_name = "get"]
    pub fn curl_get(url: String) -> String;



This struct contains parameters that would be accessible by Wasm modules.

Describes result of calling a CLI service.

The same as the MountedBinaryResult, but stdout and stderr are utf8 strings.

Describes an origin that set corresponding value.

The Wasm logger builder.



Type Definitions

Mapping from logging namespace string to its bitmask. TODO: use i64 for bitmask when wasmpack/bindgen issue with i64 is fixed. Currently, i64 doesn’t work on some versions of V8 because log_utf8_string function isn’t marked as #[wasm_bindgen]. In result, TS/JS code throws ‘TypeError’ on every log.
