Struct GenerateShadowfork 

pub(crate) struct GenerateShadowfork {
    output: PathBuf,
    force: bool,
    source_chain: String,
    execution_datadir: PathBuf,
    block: BlockTarget,
    preserve_chain_id: bool,
    genesis_args: GenesisArgs,
}

Generates artifacts for a private shadow fork from a local Tempo execution datadir.

The source node must be stopped before using its datadir. The resulting network is expected to run private consensus from the generated artifacts and not follow the source chain after startup.

Fields

output: PathBuf

The target directory that will be populated.

If this directory exists but is not empty the operation will fail unless --force is specified. In this case the target directory will be first cleaned.

force: bool

Whether to overwrite output.

source_chain: String

Human-readable source chain name recorded in the manifest.

execution_datadir: PathBuf

Source execution datadir, chain datadir, or db directory to fork from.

block: BlockTarget

Source block to fork from: latest, a decimal block number, or a block hash.

The selected block must be the local datadir tip.

preserve_chain_id: bool

Keep the source chain ID in the generated genesis.

genesis_args: GenesisArgs
