This Cargo feature is required to compile or run Wasm that uses any of the following Wasm proposals:
- Reference types: https://github.com/WebAssembly/reference-types/
- Typed function references: https://github.com/WebAssembly/function-references/
- Garbage collection: https://github.com/WebAssembly/gc
When a compiler Cargo feature (
craneliftorwinch) is enabled, this feature gates the ability to compile Wasm that uses those proposals.When the
runtimeCargo feature is enabled, this feature gates the ability to load and run Wasm that uses those proposals.
Features from optional dependencies
In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
