Struct polkadot_node_core_pvf::ValidationHost

pub struct ValidationHost {
    pub security_status: SecurityStatus,
    /* private fields */
}

A handle to the async process serving the validation host requests.

Fields

security_status: SecurityStatus

Available security features, detected by the host during startup.

Implementations

impl ValidationHost

pub async fn precheck_pvf( &mut self, pvf: PvfPrepData, result_tx: Sender<PrecheckResult>, ) -> Result<(), String>

Precheck PVF with the given code, i.e. verify that it compiles within a reasonable time limit. This will prepare the PVF. The result of preparation will be sent to the provided result sender.

This is async to accommodate the possibility of back-pressure. In the vast majority of situations this function should return immediately.

Returns an error if the request cannot be sent to the validation host, i.e. if it shut down.

pub async fn execute_pvf( &mut self, pvf: PvfPrepData, exec_timeout: Duration, pvd: Arc<PersistedValidationData>, pov: Arc<PoV>, priority: Priority, exec_kind: PvfExecKind, result_tx: Sender<Result<ValidationResult, ValidationError>>, ) -> Result<(), String>

Execute PVF with the given code, execution timeout, parameters and priority. The result of execution will be sent to the provided result sender.

This is async to accommodate the possibility of back-pressure. In the vast majority of situations this function should return immediately.

Returns an error if the request cannot be sent to the validation host, i.e. if it shut down.

pub async fn heads_up( &mut self, active_pvfs: Vec<PvfPrepData>, ) -> Result<(), String>

Sends a signal to the validation host requesting to prepare a list of the given PVFs.

This is async to accommodate the possibility of back-pressure. In the vast majority of situations this function should return immediately.

Returns an error if the request cannot be sent to the validation host, i.e. if it shut down.

pub async fn update_active_leaves( &mut self, update: ActiveLeavesUpdate, ancestors: Vec<Hash>, ) -> Result<(), String>

Sends a signal to the validation host requesting to update best block.

Returns an error if the request cannot be sent to the validation host, i.e. if it shut down.

Trait Implementations

impl Clone for ValidationHost

fn clone(&self) -> ValidationHost

Returns a copy of the value.

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

Performs copy-assignment from source.
