This crate depends on the WasmEdge C API. In linux/macOS the crate can download the API at build time by enabling the standalone feature. Otherwise the API needs to be installed in your system first. Please refer to Install and uninstall WasmEdge 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, rust-lang/rust-bindgen#2333).
Notice: The minimum supported Rust version is 1.71.
If you are upgrading from 0.13.2 to 0.14.0, refer to docs/Upgrade_to_0.14.0.md.
The Examples of WasmEdge RustSDK repo contains a number of examples that demonstrate how to use the WasmEdge Rust SDK.
