Type Alias SyscallResult 

pub type SyscallResult<T> = Result<T, ErrorNumber>;

SDK functions performing a syscall return a SyscallResult type, where the Error type is an ExitCode. ExitCode::Ok is translated to an Ok result, while error codes are propagated as Err(ExitCode).

Error messages don’t make it across the boundary, but are logged at the FVM level for debugging and informational purposes.

    Ok(T),
    Err(ErrorNumber),
}
