This project aims to give a low-level and a high-level binding to ewasm from Rust.

Usage

Add the dependency, as usual:

[dependencies]
ewasm-api = "0.11"

Make sure the project is a library of cdylib type:

[lib]
crate-type = ["cdylib"]

In your project, include the prelude:

use ewasm_api::prelude::*;

Additionally there is support for some macros to make creating contracts easier:

#[macro_use]
extern crate ewasm_api;

use ewasm_api::prelude::*;

fn entry() {
    // The actual contract code goes here.
}

ewasm_entry_point!(entry);

Other modules are available as well, outside of the prelude. Refer to the documentation for more info.

ewasm-rust-api builds with various feature sets:

• default: Builds with wee_alloc as the global allocator and with the Rust standard library.
• qimalloc: Builds with qimalloc as the global allocator.
• debug: Exposes the debugging interface.
• experimental: Exposes the experimental bignum system library API.

To enable specific features include the dependency as follows:

[dependencies.ewasm_api]
version = "0.11"
default-features = false
features = ["std", "qimalloc"]

Further documentation is available here.
