This project aims to give a low-level and a high-level binding to ewasm from Rust.
Add the dependency, as usual:
toml
[dependencies]
ewasm-api = "0.11"
Make sure the project is a library of cdylib type:
toml
[lib]
crate-type = ["cdylib"]
In your project, include the prelude:
rust
use ewasm_api::prelude::*;
Additionally there is support for some macros to make creating contracts easier: ```rust
extern crate ewasm_api;
use ewasm_api::prelude::*;
fn entry() { // The actual contract code goes here. }
ewasmentrypoint!(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:
toml
[dependencies.ewasm_api]
version = "0.11"
default-features = false
features = ["std", "qimalloc"]
Further documentation is available here.
