pub struct NativeElseWasmExecutor<D>where
    D: NativeExecutionDispatch,{ /* 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§

source§

impl<D> NativeElseWasmExecutor<D>where D: NativeExecutionDispatch,

source

pub fn new( fallback_method: WasmExecutionMethod, default_heap_pages: Option<u64>, max_runtime_instances: usize, runtime_cache_size: u8 ) -> NativeElseWasmExecutor<D>

👎Deprecated: use Self::new_with_wasm_executor method instead of it

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. Internally this will be mapped as HeapAllocStrategy::Static where default_heap_pages represent the static number of heap pages to allocate. Defaults to DEFAULT_HEAP_ALLOC_STRATEGY if None is provided.

max_runtime_instances - The number of runtime instances to keep in memory ready for reuse.

runtime_cache_size - The capacity of runtime cache.

source

pub fn new_with_wasm_executor( executor: WasmExecutor<ExtendedHostFunctions<(HostFunctions, HostFunctions, HostFunctions, HostFunctions, HostFunctions, HostFunctions, HostFunctions, HostFunctions, HostFunctions, HostFunctions, HostFunctions, HostFunctions, HostFunctions), <D as NativeExecutionDispatch>::ExtendHostFunctions>> ) -> NativeElseWasmExecutor<D>

Create a new instance using the given WasmExecutor.

source

pub fn allow_missing_host_functions( &mut self, allow_missing_host_functions: bool )

👎Deprecated: use Self::new_with_wasm_executor method instead of it

Ignore missing function imports if set true.
