Description
What happened?
Trying out hyperlight-host 0.3 with code:
use hyperlight_host::{
MultiUseSandbox, UninitializedSandbox, func::ReturnType, sandbox_state::transition::Noop,
};
fn main() -> hyperlight_host::Result<()> {
let mut uninitialized_sandbox = UninitializedSandbox::new(
hyperlight_host::GuestBinary::FilePath("".to_string()),
None, // default configuration
None, // default run options
None, // default host print function
)?;
Ok(())
}
Failed to build with error:
error[E0277]: `?` couldn't convert the error to `HyperlightError`
--> /home/magicloud/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/hyperlight-host-0.3.0/src/hypervisor/hyperv_linux.rs:586:56

586 | let io_message = m.to_ioport_info()?;
| ----------------^ the trait `From<vmm_sys_util::errno::Error>` is not implemented for `HyperlightError`
| |
| this can't be annotated with `?` because it has type `Result<_, vmm_sys_util::errno::Error>`
|
note: `HyperlightError` needs to implement `From<vmm_sys_util::errno::Error>`

| ^^^^^^^^^^^^^^^^^^^^^^^^
= note: the question mark operation (`?`) implicitly performs a conversion on the error value using the `From` trait
= help: the following other types implement trait `From<T>`:
`HyperlightError` implements `From<&str>`
`HyperlightError` implements `From<BackendError>`
`HyperlightError` implements `From<BorrowError>`
`HyperlightError` implements `From<BorrowMutError>`
`HyperlightError` implements `From<FromUtf8Error>`
`HyperlightError` implements `From<Infallible>`
`HyperlightError` implements `From<InvalidFlatbuffer>`
`HyperlightError` implements `From<MshvError>`
and 14 others
And same error at some other places.
What did you expect to happen?
Testing code pass building.
