Struct sc_cli::ImportParams

pub struct ImportParams {
    pub pruning_params: PruningParams,
    pub database_params: DatabaseParams,
    pub wasm_method: WasmExecutionMethod,
    pub wasmtime_instantiation_strategy: WasmtimeInstantiationStrategy,

}

Parameters for block import.

Fields

pruning_params: PruningParams

database_params: DatabaseParams

wasm_method: WasmExecutionMethod

Method for executing Wasm runtime code.

wasmtime_instantiation_strategy: WasmtimeInstantiationStrategy

The WASM instantiation method to use.

Only has an effect when wasm-execution is set to compiled.

The copy-on-write strategies are only supported on Linux. If the copy-on-write variant of a strategy is unsupported the executor will fall back to the non-CoW equivalent.

The fastest (and the default) strategy available is pooling-copy-on-write.

The legacy-instance-reuse strategy is deprecated and will be removed in the future. It should only be used in case of issues with the default instantiation strategy.

wasm_runtime_overrides: Option<PathBuf>

Specify the path where local WASM runtimes are stored.

These runtimes will override on-chain runtimes when the version matches.

execution_strategies: ExecutionStrategiesParams

trie_cache_size: usize

Specify the state cache size.

Providing 0 will disable the cache.

Implementations

impl ImportParams

pub fn trie_cache_maximum_size(&self) -> Option<usize>

Specify the trie cache maximum size.

pub fn wasm_method(&self) -> WasmExecutionMethod

Get the WASM execution method from the parameters

pub fn wasm_runtime_overrides(&self) -> Option<PathBuf>

Enable overriding on-chain WASM with locally-stored WASM by specifying the path where local WASM is stored.

pub fn execution_strategies(
    &self,
    is_dev: bool,
    is_validator: bool
) -> ExecutionStrategies

Get execution strategies for the parameters

Trait Implementations

impl Args for ImportParams

fn group_id() -> Option<Id>

Report the ArgGroup::id for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate Self.

fn augment_args_for_update<'b>(__clap_app: Command) -> Command

Append to Command so it can update self.

impl Clone for ImportParams

fn clone(&self) -> ImportParams

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ImportParams

fn fmt(&self, f: &mut Formatter<'_>) -> Result
