        chain_spec_path: PathBuf,
        keystore_path: Option<PathBuf>,
    },
}

A utility to easily create a testnet chain spec definition with a given set of authorities and endowed accounts and/or generate random accounts.

Variants

New

Create a new chain spec with the given authorities, endowed and sudo accounts.

Fields of New

authority_seeds: Vec<String>

Authority key seed.

nominator_accounts: Vec<String>

Active nominators (SS58 format), each backing a random subset of the aforementioned authorities.

endowed_accounts: Vec<String>

Endowed account address (SS58 format).

sudo_account: String

Sudo account address (SS58 format).

chain_spec_path: PathBuf

The path where the chain spec should be saved.

Generate

Create a new chain spec with the given number of authorities and endowed accounts. Random keys will be generated as required.

Fields of Generate

authorities: usize

The number of authorities.

nominators: usize

The number of nominators backing the aforementioned authorities.

Will nominate a random subset of authorities.

endowed: usize

The number of endowed accounts.

chain_spec_path: PathBuf

The path where the chain spec should be saved.

keystore_path: Option<PathBuf>

Path to use when saving generated keystores for each authority.

At this path, a new folder will be created for each authority’s keystore named auth-$i where i is the authority index, i.e. auth-0, auth-1, etc.

Implementations

impl ChainSpecBuilder

pub(crate) fn chain_spec_path(&self) -> &Path

Returns the path where the chain spec should be saved.

Trait Implementations

impl StructOpt for ChainSpecBuilder

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.
