Struct sc_executor::NativeExecutor

source · [−]

pub struct NativeExecutor<D> { /* private fields */ }

Expand description

A generic CodeExecutor implementation that uses a delegate to determine wasm code equivalence and dispatch to native code when possible, falling back on WasmExecutor when not.

Implementations

impl<D: NativeExecutionDispatch> NativeExecutor<D>

pub fn new(
    fallback_method: WasmExecutionMethod,
    default_heap_pages: Option<u64>,
    max_runtime_instances: usize
) -> Self

Create new instance.

Parameters

fallback_method - Method used to execute fallback Wasm code.

default_heap_pages - Number of 64KB pages to allocate for Wasm execution. Defaults to DEFAULT_HEAP_PAGES if None is provided.
