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