Implementations§
§impl ActnCallback
impl ActnCallback
pub fn new(
actn_fn: impl Fn(ActnCallbackParam<'_>) -> bool + 'static + Send,
) -> Self
pub fn new( actn_fn: impl Fn(ActnCallbackParam<'_>) -> bool + 'static + Send, ) -> Self
Creates a new callback instance.
The supplied actn_fn will be called whenever a PolicyAction element is encountered during policy evaluation. The purpose and reaction to such an event is application dependent. This function receives a ActnCallbackParam as parameter.
pub fn with_data<T: 'static + Send>(
actn_fn: impl Fn(ActnCallbackParam<'_>, &T) -> bool + 'static + Send,
extra_data: T,
) -> Self
pub fn with_data<T: 'static + Send>( actn_fn: impl Fn(ActnCallbackParam<'_>, &T) -> bool + 'static + Send, extra_data: T, ) -> Self
Creates a new callback instance with additional data.
The supplied actn_fn will be called whenever a PolicyAction element is encountered during policy evaluation. The purpose and reaction to such an event is application dependent. This function receives a ActnCallbackParam as parameter.
The application-defined extra_data argument will be passed to each invocation of actn_fn as an additional parameter.
