Proc Macro For externref

Build Status License: MIT OR Apache-2.0 rust 1.60+ required

Documentation: crate docs (main)

This macro complements the externref library, wrapping imported or exported functions with Resource args and/or return type. These wrappers are what makes it possible to patch the generated WASM module with the externref processor, so that real externrefs are used in argument / return type positions.


Add this to your Crate.toml:

externref-macro = "0.1.0"

Note that the externref crate re-exports the proc macro if the macro crate feature is enabled (which it is by default). Thus, it is rarely necessary to use this crate as a direct dependency.

See externref docs for more details and examples of usage.
