Enum HookReturnValue

pub enum HookReturnValue {
    CallNextHook,
    BlockMessage,
    PassToWindowProcOnly,
    ExplicitValue(LRESULT),
}

Available on crate feature hooking only.

A value indicating what action should be taken after returning from the user callback in LowLevelInputHook::run_hook.

Variants

CallNextHook

Returns the result of calling [CallNextHookEx] with the original raw message, allowing further processing by other hooks.

PassToWindowProcOnly

Passes the event to the target window procedure but not the rest of the hook chain.

ExplicitValue(LRESULT)
