Enum RoamError 

#[repr(u8)]
pub enum RoamError<E = Infallible> {
    User(E),
    UnknownMethod,
    InvalidPayload,
    Cancelled,
}

Protocol-level error wrapper distinguishing application errors from roam infrastructure errors.

On the caller side, all return types are wrapped as Result<T, RoamError<E>>:

• Infallible fn foo() -> T becomes Result<T, RoamError>
• Fallible fn foo() -> Result<T, E> becomes Result<T, RoamError<E>>

Variants

User(E)

The handler ran and returned an application error.

UnknownMethod

No handler recognized the method ID.

InvalidPayload

The arguments could not be deserialized.

Cancelled

The call was cancelled before completion.
