Struct fuel_indexer::executor::WasmIndexExecutor

pub struct WasmIndexExecutor { /* private fields */ }

WASM executors are the primary means of execution.

WASM executors contain a WASM module that is instantiated and executed by the indexer service on a virtually infinite tokio task loop. These executors are responsible for allocating/deallocating their own memory for calls in and out of the runtime.

Implementations

impl WasmIndexExecutor

pub async fn new( config: &IndexerConfig, manifest: &Manifest, wasm_bytes: impl AsRef<[u8]>, pool: IndexerConnectionPool, schema_version: String ) -> IndexerResult<Self>

Create a new WasmIndexExecutor.

pub async fn from_file( p: impl AsRef<Path>, config: Option<IndexerConfig>, pool: IndexerConnectionPool ) -> IndexerResult<WasmIndexExecutor>

Restore index from wasm file

pub async fn create( config: &IndexerConfig, manifest: &Manifest, pool: IndexerConnectionPool, schema_version: String, wasm_bytes: impl AsRef<[u8]> ) -> IndexerResult<Self>

Create a new WasmIndexExecutor.

pub fn metering_enabled(&self) -> bool

Returns true if metering is enabled.

pub async fn metering_points_exhausted(&self) -> bool

Returns true if metering is enabled metering points are exhausted. Otherwise returns false.

pub async fn get_remaining_metering_points(&self) -> Option<MeteringPoints>

Returns remaining metering points if metering is enabled. Otherwise, returns None.

pub async fn set_metering_points( &self, metering_points: u64 ) -> IndexerResult<()>

Sets the remaining metering points if metering is enabled. Otherwise, returns an error.
