Trait Implementations

impl<A> Clone for DefaultHost<A>

where A: Clone,

fn clone(&self) -> DefaultHost<A>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for DefaultHost<MemAdviceProvider>

fn default() -> DefaultHost<MemAdviceProvider>

Returns the “default value” for a type.

impl<A> Host for DefaultHost<A>

where A: AdviceProvider,

fn get_advice<P>( &mut self, process: &P, extractor: AdviceExtractor, ) -> Result<HostResponse, ExecutionError>

where P: ProcessState,

Returns the requested advice, specified by AdviceExtractor, from the host to the VM.

fn set_advice<P>( &mut self, process: &P, injector: AdviceInjector, ) -> Result<HostResponse, ExecutionError>

where P: ProcessState,

Sets the requested advice, specified by AdviceInjector, on the host.

fn get_mast_forest(&self, node_digest: &RpoDigest) -> Option<Arc<MastForest>>

Returns MAST forest corresponding to the specified digest, or None if the MAST forest for this digest could not be found in this Host.

fn by_ref(&mut self) -> &mut Self

Creates a “by reference” host for this instance.

fn on_event<S>( &mut self, _process: &S, _event_id: u32, ) -> Result<HostResponse, ExecutionError>

where S: ProcessState,

Handles the event emitted from the VM.

fn on_debug<S>( &mut self, _process: &S, _options: &DebugOptions, ) -> Result<HostResponse, ExecutionError>

where S: ProcessState,

fn pop_adv_stack_dword<S>( &mut self, process: &S, ) -> Result<[[BaseElement; 4]; 2], ExecutionError>

where S: ProcessState,

Pops a double word (8 elements) from the advice stack and returns them.

fn get_adv_merkle_path<S>( &mut self, process: &S, ) -> Result<MerklePath, ExecutionError>

where S: ProcessState,
