Crate wasmi_c_api

Expand description

Implements C-API support for the Wasmi WebAssembly interpreter.

Namely implements the Wasm C-API proposal found here: https://github.com/WebAssembly/wasm-c-api/

§Crate features

§The `prefix-symbols` feature

Adds a wasmi_ prefix to all the public symbols. This means that, for example, the function wasm_store_delete will be given the public (not mangled) symbol wasmi_wasm_store_delete.

§Rationale

This feature allows users that need to separate multiple C-API implementers to segregate wasmi’s C-API symbols, avoiding symbol clashes.

§Note

It’s important to notice that when the prefix-symbols feature is enabled, the symbols declared in the C-API header are not given the prefix, introducing - by design, in order to keep the C-API header same as the actual specification - an asymmetry. For example, Rust users that want to enable this feature, can use bindgen to generate correct C-to-Rust interop code:

   #[derive(Debug)]
   struct WasmiRenamer {}

   impl ParseCallbacks for WasmiRenamer {
       /// This function will run for every extern variable and function. The returned value determines
       /// the link name in the bindings.
       fn generated_link_name_override(
           &self,
           item_info: bindgen::callbacks::ItemInfo<'_>,
       ) -> Option<String> {
           if item_info.name.starts_with("wasm") {
               let new_name = if cfg!(any(target_os = "macos", target_os = "ios")) {
                   format!("_wasmi_{}", item_info.name)
               } else {
                   format!("wasmi_{}", item_info.name)
               };

               Some(new_name)
           } else {
               None
           }
       }
   }

   let bindings = bindgen::Builder::default()
       .header(
           PathBuf::from(std::env::var("DEP_WASMI_C_API_INCLUDE").unwrap())
               .join("wasm.h")
               .to_string_lossy(),
       )
       .derive_default(true)
       .derive_debug(true)
       .parse_callbacks(Box::new(WasmiRenamer {}))
       .generate()
       .expect("Unable to generate bindings for `wasmi`!");
