Struct DefaultHost

pub struct DefaultHost { /* private fields */ }

A default BaseHost, SyncHost and AsyncHost implementation that provides the essential functionality required by the VM.

Implementations

impl DefaultHost

pub fn load_mast_forest( &mut self, mast_forest: Arc<MastForest>, ) -> Result<(), ExecutionError>

Trait Implementations

impl AsyncHost for DefaultHost

async fn get_mast_forest(&self, node_digest: &Word) -> 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 AsyncHost.

fn on_event( &mut self, _process: &mut ProcessState<'_>, _event_id: u32, _err_ctx: &impl ErrorContext, ) -> impl Future<Output = Result<(), ExecutionError>> + Send

Handles the event emitted from the VM.

impl BaseHost for DefaultHost

fn on_debug( &mut self, process: &mut ProcessState<'_>, options: &DebugOptions, ) -> Result<(), ExecutionError>

Handles the debug request from the VM.

fn on_trace( &mut self, process: &mut ProcessState<'_>, trace_id: u32, ) -> Result<(), ExecutionError>

Handles the trace emitted from the VM.

fn on_assert_failed(&mut self, _process: &mut ProcessState<'_>, _err_code: Felt)

Handles the failure of the assertion instruction.

impl Clone for DefaultHost

fn clone(&self) -> DefaultHost

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DefaultHost

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DefaultHost

fn default() -> DefaultHost

Returns the “default value” for a type.

impl SyncHost for DefaultHost

fn get_mast_forest(&self, node_digest: &Word) -> 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 SyncHost.

fn on_event( &mut self, process: &mut ProcessState<'_>, event_id: u32, err_ctx: &impl ErrorContext, ) -> Result<(), ExecutionError>

Handles the event emitted from the VM.
