Test Case
TODO: upload Wasm file here
no wasm. just rust.
Steps to Reproduce
- TODO: first, ...
- TODO: second, ...
- Etc...
- crate a new cargo project
- add wasmtime with the component-model feature
- use the below wit in the wit/ folder with bindgen!()
- see error
package jcbhmr:hello-world-rust-wasm-component-lib;
interface my-box {
resource my-box {
constructor(value: u32);
value: func() -> u32;
}
set-global: func(value: my-box);
global-value: func() -> u32;
}
world example {
export my-box;
}
use wasmtime::component::*;
use wasmtime::{Config, Engine, Store};
bindgen!();
Expected Results
it to either auto-rename it due to duplication or otherwise scope it so that this collision doesn't happen
Actual Results

jcbhmr@PIG-2016:~/Documents/rswasmtest$ cargo build
Compiling rswasmtest v0.1.0 (/home/jcbhmr/Documents/rswasmtest)
error[E0428]: the name `MyBox` is defined multiple times
--> src/main.rs:4:1

4 | bindgen!();
| ^^^^^^^^^^ `MyBox` redefined here

= note: `MyBox` must be defined only once in the type namespace of this module
= note: this error originates in the macro `bindgen` (in Nightly builds, run with -Z macro-backtrace for more info)
error[E0116]: cannot define inherent `impl` for a type outside of the crate where the type is defined
--> src/main.rs:4:1

4 | bindgen!();
| ^^^^^^^^^^ impl for type defined outside of crate.

= note: define and implement a trait or new type instead

Some errors have detailed explanations: E0116, E0428.
