Struct RunCmd 

pub struct RunCmd {
    pub base: RunCmd,
    pub collator: bool,
    pub relay_chain_rpc_urls: Vec<Url>,
    pub experimental_max_pov_percentage: Option<u32>,
    pub no_dht_bootnode: bool,
    pub no_dht_bootnode_discovery: bool,
}

The run command used to run a node.

Fields

base: RunCmd

The cumulus RunCmd inherents from sc_cli’s

collator: bool

Run node as collator.

Note that this is the same as running with --validator.

relay_chain_rpc_urls: Vec<Url>

Creates a less resource-hungry node that retrieves relay chain data from an RPC endpoint.

The provided URLs should point to RPC endpoints of the relay chain. This node connects to the remote nodes following the order they were specified in. If the connection fails, it attempts to connect to the next endpoint in the list.

Note: This option doesn’t stop the node from connecting to the relay chain network but reduces bandwidth use.

experimental_max_pov_percentage: Option<u32>

EXPERIMENTAL: This is meant to be used only if collator is overshooting the PoV size, and building blocks that do not fit in the max_pov_size. It is a percentage of the max_pov_size configuration of the relay-chain.

It will be removed once https://github.com/paritytech/polkadot-sdk/issues/6020 is fixed.

no_dht_bootnode: bool

Disable embedded DHT bootnode.

Do not advertise the node as a parachain bootnode on the relay chain DHT.

no_dht_bootnode_discovery: bool

Disable DHT bootnode discovery.

Disable discovery of the parachain bootnodes via the relay chain DHT.

Implementations

impl RunCmd

pub fn normalize(&self) -> NormalizedRunCmd

Create a NormalizedRunCmd which merges the collator cli argument into validator to have only one.

pub fn collator_options(&self) -> CollatorOptions

Create CollatorOptions representing options only relevant to parachain collator nodes
