//! # Overview
//!
//! WasmEdge Rust SDK provides idiomatic [Rust](https://www.rust-lang.org/) language bindings for [WasmEdge](https://wasmedge.org/)
//!
//! **Notice:** This project is still under active development and not guaranteed to have a stable API.

//! ## Get Started
//!
//! Since this crate depends on the WasmEdge C API, it needs to be installed in your system first. Please refer to [WasmEdge Installation and Uninstallation](https://wasmedge.org/book/en/quick_start/install.html) to install the WasmEdge library. The versioning table below shows the version of the WasmEdge library required by each version of the `wasmedge-sdk` crate.

//! WasmEdge Rust SDK will automatically search for the WasmEdge library in your system. Alternatively you can set the `WASMEDGE_DIR` environment variable to the path of the WasmEdge library (or the `WASMEDGE_INCLUDE_DIR` and `WASMEDGE_LIB_DIR` variables for more fine-grained control). If you want to use a local `cmake` build of WasmEdge you can set the `WASMEDGE_BUILD_DIR` instead.
//!
//! WasmEdge Rust SDK will search for the WasmEdge library in the following paths in order:
//!
//! - `$WASMEDGE_[INCLUDE|LIB]_DIR`
//! - `$WASMEDGE_DIR`
//! - `$WASMEDGE_BUILD_DIR`
//! - `$HOME/.wasmedge`
//! - `/usr/local`
//! - `$HOME/.local`
//!
//! When the `standalone` feature is enabled the correct library will be downloaded during build time and the previous locations are ignored. You can specify a proxy for the download process using the `WASMEDGE_STANDALONE_PROXY`, `WASMEDGE_STANDALONE_PROXY_USER` and `WASMEDGE_STANDALONE_PROXY_PASS` environment variables. You can set the `WASMEDGE_STANDALONE_ARCHIVE` environment variable to use a local archive instead of downloading one.
//! The following architectures are supported for automatic downloads:
//!
//! | os    | libc    | architecture        | linking type    |
//! | :---: | :-----: | :-----------------: | :-------------: |
//! | macos | -       | `x86_64`, `aarch64` | dynamic         |
//! | linux | `glibc` | `x86_64`, `aarch64` | static, dynamic |
//! | linux | `musl`  | `x86_64`, `aarch64` | static          |
//!
//! This crate uses `rust-bindgen` during the build process. If you would like to use an external `rust-bindgen` you can set the `WASMEDGE_RUST_BINDGEN_PATH` environment variable to the `bindgen` executable path. This is particularly useful in systems like Alpine Linux (see [rust-lang/rust-bindgen#2360](https://github.com/rust-lang/rust-bindgen/issues/2360#issuecomment-1595869379), [rust-lang/rust-bindgen#2333](https://github.com/rust-lang/rust-bindgen/issues/2333)).
//!
//! **Notice:** The minimum supported Rust version is 1.71.
