Struct ImportParams 

pub struct ImportParams {
    pub pruning_params: PruningParams,
    pub database_params: DatabaseParams,
    pub wasm_method: WasmExecutionMethod,
    pub wasmtime_instantiation_strategy: WasmtimeInstantiationStrategy,
    pub wasm_runtime_overrides: Option<PathBuf>,
    pub execution_strategies: ExecutionStrategiesParams,
    pub trie_cache_size: usize,
    pub warm_up_trie_cache: Option<TrieCacheWarmUpStrategy>,
}

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.

warm_up_trie_cache: Option<TrieCacheWarmUpStrategy>

Warm up the trie cache.

No warmup if flag is not present. Using flag without value chooses non-blocking warmup.

Implementations

impl ImportParams

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

Specify the trie cache maximum size.

pub fn warm_up_trie_cache(&self) -> Option<TrieCacheWarmUpStrategy>

Specify if we should warm up the trie cache.

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.

Trait Implementations

impl Args for ImportParams
