Struct sc_cli::ImportParams

pub struct ImportParams {
    pub pruning_params: PruningParams,
    pub database_params: DatabaseParams,
    pub unsafe_pruning: bool,
    pub wasm_method: WasmExecutionMethod,
    pub wasm_runtime_overrides: Option<PathBuf>,
    pub execution_strategies: ExecutionStrategiesParams,
    pub state_cache_size: usize,
}

Parameters for block import.

Fields

pruning_params: PruningParams

database_params: DatabaseParams

unsafe_pruning: bool

Force start with unsafe pruning settings.

When running as a validator it is highly recommended to disable state pruning (i.e. ‘archive’) which is the default. The node will refuse to start as a validator if pruning is enabled unless this option is set.

wasm_method: WasmExecutionMethod

Method for executing Wasm runtime code.

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

state_cache_size: usize

Specify the state cache size.

Implementations

impl ImportParams

pub fn state_cache_size(&self) -> usize

Specify the state cache 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 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

Formats the value using the given formatter.

impl StructOpt for ImportParams

fn clap<'a, 'b>() -> App<'a, 'b>

Returns clap::App corresponding to the struct.

fn from_clap(matches: &ArgMatches<'_>) -> Self

Builds the struct from clap::ArgMatches. It’s guaranteed to succeed if matches originates from an App generated by [StructOpt::clap] called on the same type, otherwise it must panic.

fn from_args() -> Self

Builds the struct from the command line arguments (std::env::args_os). Calls clap::Error::exit on failure, printing the error message and aborting the program.

fn from_args_safe() -> Result<Self, Error>

Builds the struct from the command line arguments (std::env::args_os). Unlike [StructOpt::from_args], returns clap::Error on failure instead of aborting the program, so calling .exit is up to you.

fn from_iter<I>(iter: I) -> Self where
    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString>,
    <I as IntoIterator>::Item: Clone, 

Gets the struct from any iterator such as a Vec of your making. Print the error message and quit the program in case of failure.

fn from_iter_safe<I>(iter: I) -> Result<Self, Error> where
    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString>,
    <I as IntoIterator>::Item: Clone, 

Gets the struct from any iterator such as a Vec of your making.
