Struct sc_executor::WasmExecutor [−][src]
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]
method: WasmExecutionMethod,
default_heap_pages: Option<u64>,
host_functions: Vec<&'static dyn Function>,
max_runtime_instances: usize,
cache_path: Option<PathBuf>
) -> Self
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.
