Crate wasm_minimal_protocol

Minimal protocol for sending/receiving messages from and to a wasm host.

If you define a function accepting n arguments of type &[u8], it will internally be exported as a function accepting n integers.

Example

use wasm_minimal_protocol::wasm_func;

#[cfg(target_arch = "wasm32")]
wasm_minimal_protocol::initiate_protocol!();

#[cfg_attr(target_arch = "wasm32", wasm_func)]
fn concatenate(arg1: &[u8], arg2: &[u8]) -> Vec<u8> {
    [arg1, arg2].concat()
}

Protocol

The specification of the protocol can be found in the typst documentation: https://typst.app/docs/reference/foundations/plugin/#protocol

Macros

initiate_protocol

Macro that sets up the correct imports and traits to be used by wasm_func.

Attribute Macros
