Struct sc_cli::DatabaseParams

pub struct DatabaseParams {
    pub database: Option<Database>,
    pub database_cache_size: Option<usize>,
    pub storage_chain: bool,
}

Parameters for block import.

Fields

database: Option<Database>

Select database backend to use.

database_cache_size: Option<usize>

Limit the memory the database cache can use.

storage_chain: bool

Enable storage chain mode

This changes the storage format for blocks bodys. If this is enabled, each transaction is stored separately in the transaction database column and is only referenced by hash in the block body column.

Implementations

impl DatabaseParams

pub fn database(&self) -> Option<Database>

Limit the memory the database cache can use.

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

Limit the memory the database cache can use.

pub fn transaction_storage(&self) -> TransactionStorageMode

Transaction storage scheme.

Trait Implementations

impl Debug for DatabaseParams

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

Formats the value using the given formatter.

impl StructOpt for DatabaseParams

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.
