Struct InjectorHandler 

pub struct InjectorHandler<Os, Mode, T, Bridge = ()>
where
    Os: InjectorExecutionAdapter<Mode, T, Bridge>,
    Mode: ExecutionMode,
    Bridge: BridgeDispatch<Os, u64>,
{ /* private fields */ }

Available on crate features injector and utils only.

Generic injector handler that delegates to an OS- and mode-specific implementation.

Prefer the KernelInjectorHandler and UserInjectorHandler type aliases for the common case without a bridge. When a custom BridgeDispatch is needed, use this type directly with an explicit Bridge parameter.

Implementations

impl<Os, Mode, T, Bridge> InjectorHandler<Os, Mode, T, Bridge>

where Os: InjectorExecutionAdapter<Mode, T, Bridge>, Mode: ExecutionMode, Bridge: BridgeDispatch<Os, u64>,

pub fn new( vmi: &VmiSession<'_, Os>, recipe: Recipe<Os, T>, ) -> Result<InjectorHandler<Os, Mode, T, Bridge>, VmiError>

where Bridge: Default,

Creates a new injector handler with a default (no-op) bridge.

impl<Os, Mode, T, Bridge> VmiHandler<Os> for InjectorHandler<Os, Mode, T, Bridge>

where Os: InjectorExecutionAdapter<Mode, T, Bridge>, Mode: ExecutionMode, Bridge: BridgeDispatch<Os, u64>,

type Output = <<Os as InjectorExecutionAdapter<Mode, T, Bridge>>::Handler as VmiHandler<Os>>::Output

The output type of the handler.

fn handle_event( &mut self, vmi: VmiContext<'_, Os>, ) -> VmiEventResponse<<Os as VmiOs>::Architecture>

Called for each VMI event.
