Struct frequency_cli::ExportMetadataCmd

pub struct ExportMetadataCmd {
    pub output: Option<PathBuf>,
    pub from: Option<GenericNumber>,
    pub shared_params: SharedParams,
    pub tmp: bool,
}

The export-metadata command used to export chain metadata. Remember that this uses the chain database. So it will pull the current metadata from that database.

Fields

output: Option<PathBuf>

Output file name or stdout if unspecified.

from: Option<GenericNumber>

Specify starting block number.

Default is 0.

shared_params: SharedParams

tmp: bool

Use a temporary directory for the db

A temporary directory will be created to store the configuration and will be deleted at the end of the process.

Note: the directory is random per process execution. This directory is used as base path which includes: database, node key and keystore.
