Struct sc_cli::DatabaseParams

[+] Show declaration

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

[−] Expand description

Parameters for block import.

Fields

database: Option<Database>

[−] Expand description

Select database backend to use.

database_cache_size: Option<usize>

[−] Expand description

Limit the memory the database cache can use.

storage_chain: bool

[−] Expand description

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

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

Formats the value using the given formatter.

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.

pub 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.

pub 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.

pub 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.

pub 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.
