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.

Variants

CallNextHook

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

BlockMessage

PassToWindowProcOnly

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

ExplicitValue(LRESULT)

impl Eq for HookReturnValue

impl PartialEq for HookReturnValue

fn eq(&self, other: &HookReturnValue) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
