hello_rust

Rust wasm plugin example

This is a bare-bone typst plugin, written in Rust. It uses the wasm-minimal-protocol crate to easily define plugin functions.

Compile

To compile this example, you need to have a working Rust toolchain. Then we need to install the wasm32-unknown-unknown target:

rustup target add wasm32-unknown-unknown

Then, build the crate with this target:

cargo build --release --target wasm32-unknown-unknown
cp ./target/wasm32-unknown-unknown/release/hello.wasm ./

Compile with wasi

If you want to build with WASI, use the wasm32-wasi target:

rustup target add wasm32-wasi
cargo build --release --target wasm32-wasi

Then, stub the resulting binary:

pushd ../../wasi-stub
cargo run -- ../examples/hello_rust/target/wasm32-wasi/release/hello.wasm -o ../examples/hello_rust/hello-wasi.wasm
popd

Build with typst

Simply run typst compile hello.typ, and observe that it works !
