Struct polkadot_node_core_pvf::ValidationHost

pub struct ValidationHost { /* private fields */ }

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

Implementations

impl ValidationHost

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

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

This is async to accommodate the fact a 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: Pvf,
    execution_timeout: Duration,
    params: Vec<u8>,
    priority: Priority,
    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 fact a 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<Pvf>) -> Result<(), String>

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

This is async to accommodate the fact a 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.
