# spark-internal-rs
|
|
|
|
Rust WebAssembly functions for spark-internal.
|
|
|
|
## Installing build tools
|
|
|
|
First, we need to install Rust. Though it is possible to install it using Homebrew, we recommend installing `rustup` using the approach on the Rust homepage:
|
|
|
|
https://www.rust-lang.org/tools/install
|
|
|
|
It will most likely involve simply running:
|
|
```
|
|
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
|
|
```
|
|
|
|
Once you have `rustup` and Rust, we need to install dependencies for building Rust Wasm.
|
|
```
|
|
rustup target add wasm32-unknown-unknown
|
|
cargo install wasm-pack
|
|
```
|
|
|
|
## Building
|
|
|
|
Run the following script inside `spark-internal/rust`:
|
|
```
|
|
./build_rust_wasm.sh
|
|
```
|
|
|
|
You can also build it manually by running these commands:
|
|
```
|
|
cd spark-internal-rs
|
|
wasm-pack build --target web
|
|
```
|
|
|
|
The generated files will be in the `pkg/` subdirectory, which is already symlinked in `spark-internal/package.json`.
