Module host_function_call

Functions

call_host_function

Call a host function with the given parameters and return type. This function serializes the function call and its parameters, sends it to the host, and then retrieves the return value.

call_host_function_internal

Internal function to call a host function without generic type parameters. This is used by both the Rust and C APIs to reduce code duplication.

debug_print

Prints a message using OutBAction::DebugPrint. It transmits bytes of a message through several VMExists and, with such, it is slower than print_output_with_host_print.

get_host_return_value

Get a return value from a host function call. This usually requires a host function to be called first using call_host_function_internal. When calling call_host_function<T>, this function is called internally to get the return value.

outb

print_output_with_host_print

Print a message using the host’s print function.
