Struct sc_executor::WasmExecutor[−][src]

pub struct WasmExecutor { /* fields omitted */ }

An abstraction over Wasm code executor. Supports selecting execution backend and manages runtime cache.

Implementations

`impl WasmExecutor`[src]

`pub fn new( method: WasmExecutionMethod, default_heap_pages: Option<u64>, host_functions: Vec<&'static dyn Function>, max_runtime_instances: usize, cache_path: Option<PathBuf> ) -> Self`[src]

Create new instance.

Parameters

method - Method used to execute Wasm code.

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

host_functions - The set of host functions to be available for import provided by this executor.

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

cache_path - A path to a directory where the executor can place its files for purposes of caching. This may be important in cases when there are many different modules with the compiled execution method is used.
