Function init 

pub fn init(module_name: &str) -> Result<()>

Resolves the Mono API by locating exports in the named module.

The module must already be loaded in the current process — this function calls GetModuleHandleW, not LoadLibraryW. Call this once, as early as possible in your injected code, before any thread attaches or any handle is created.

Errors

• MonoError::DllNotFound if no module with module_name is currently loaded.
• MonoError::FnNotFound if a required export is missing from the module (unexpected for standard Mono builds).
• MonoError::AlreadyInitialized if init has already been called successfully.
