Struct RelaychainConfigBuilder 

pub struct RelaychainConfigBuilder<State> { /* private fields */ }

A relay chain configuration builder, used to build a RelaychainConfig declaratively with fields validation.

Implementations

impl<A> RelaychainConfigBuilder<A>

pub fn with_post_process_script(self, script: impl Into<String>) -> Self

Set an optional post-process script to run after chain-spec generation for this relaychain.

impl RelaychainConfigBuilder<Initial>

pub fn new( validation_context: Rc<RefCell<ValidationContext>>, ) -> RelaychainConfigBuilder<Initial>

pub fn with_chain<T>(self, chain: T) -> RelaychainConfigBuilder<WithChain>

where T: TryInto<Chain>, T::Error: Error + Send + Sync + 'static,

Set the chain name (e.g. rococo-local).

impl RelaychainConfigBuilder<WithChain>

pub fn with_default_command<T>(self, command: T) -> Self

where T: TryInto<Command>, T::Error: Error + Send + Sync + 'static,

Set the default command used for nodes. Can be overridden.

pub fn with_default_image<T>(self, image: T) -> Self

where T: TryInto<Image>, T::Error: Error + Send + Sync + 'static,

Set the default container image used for nodes. Can be overridden.

pub fn with_default_resources( self, f: impl FnOnce(ResourcesBuilder) -> ResourcesBuilder, ) -> Self

Set the default resources limits used for nodes. Can be overridden.

pub fn with_default_db_snapshot( self, location: impl Into<AssetLocation>, ) -> Self

Set the default database snapshot location that will be used for state. Can be overridden.

pub fn with_default_args(self, args: Vec<Arg>) -> Self

Set the default arguments that will be used to execute the node command. Can be overridden.

pub fn with_chain_spec_path(self, location: impl Into<AssetLocation>) -> Self

Set the location of a pre-existing chain specification for the relay chain.

pub fn with_wasm_override(self, location: impl Into<AssetLocation>) -> Self

Set the location of a wasm to override the chain-spec.

pub fn with_chain_spec_command(self, cmd_template: impl Into<String>) -> Self

Set the chain-spec command template for the relay chain.

pub fn with_chain_spec_runtime( self, location: impl Into<AssetLocation>, preset: Option<&str>, ) -> Self

Set the runtime path to use for generating the chain-spec and an optiona preset. If the preset is not set, we will try to match [local_testnet, development, dev] with the available ones and fallback to the default configuration as last option.

pub fn chain_spec_command_is_local(self, choice: bool) -> Self

Set if the chain-spec command needs to be run locally or not (false by default)

pub fn with_override_session_0(self, choice: bool) -> Self

Set to true to override session 0 and allow paras to produce blocks from genesis.

pub fn with_chain_spec_command_output_path(self, output_path: &str) -> Self

Set the output path for the chain-spec command.

pub fn with_random_nominators_count(self, random_nominators_count: u32) -> Self

Set the number of random nominators to create for chains using staking, this is used in tandem with max_nominations to simulate the amount of nominators and nominations.

pub fn with_max_nominations(self, max_nominations: u8) -> Self

Set the maximum number of nominations to create per nominator.

pub fn with_genesis_overrides(self, genesis_overrides: impl Into<Value>) -> Self

Set the genesis overrides as a JSON object.

pub fn with_validator( self, f: impl FnOnce(NodeConfigBuilder<Initial>) -> NodeConfigBuilder<Buildable>, ) -> RelaychainConfigBuilder<WithAtLeastOneNode>

Add a new validator node using a nested NodeConfigBuilder. The node will be configured as a validator (authority) with the –validator flag.

pub fn with_fullnode( self, f: impl FnOnce(NodeConfigBuilder<Initial>) -> NodeConfigBuilder<Buildable>, ) -> RelaychainConfigBuilder<WithAtLeastOneNode>

Add a new full node using a nested NodeConfigBuilder. The node will be configured as a full node (non-validator).

pub fn with_node( self, f: impl FnOnce(NodeConfigBuilder<Initial>) -> NodeConfigBuilder<Buildable>, ) -> RelaychainConfigBuilder<WithAtLeastOneNode>

👎Deprecated since 0.4.0: Use with_validator() for validator nodes or with_fullnode() for full nodes instead

Add a new node using a nested NodeConfigBuilder.

Deprecated: Use [with_validator] for validator nodes or [with_fullnode] for full nodes instead.

pub fn with_node_group( self, f: impl FnOnce(GroupNodeConfigBuilder<Initial>) -> GroupNodeConfigBuilder<Buildable>, ) -> RelaychainConfigBuilder<WithAtLeastOneNode>

Add a new group node using a nested GroupNodeConfigBuilder.

pub fn with_raw_spec_override(self, overrides: impl Into<JsonOverrides>) -> Self

Set the location or inline value of a json to override the raw chain-spec.

impl RelaychainConfigBuilder<WithAtLeastOneNode>

pub fn with_validator( self, f: impl FnOnce(NodeConfigBuilder<Initial>) -> NodeConfigBuilder<Buildable>, ) -> RelaychainConfigBuilder<WithAtLeastOneNode>

Add a new validator node using a nested NodeConfigBuilder. The node will be configured as a validator (authority) with the –validator flag.

pub fn with_fullnode( self, f: impl FnOnce(NodeConfigBuilder<Initial>) -> NodeConfigBuilder<Buildable>, ) -> Self

Add a new full node using a nested NodeConfigBuilder. The node will be configured as a full node (non-validator).

pub fn with_node( self, f: impl FnOnce(NodeConfigBuilder<Initial>) -> NodeConfigBuilder<Buildable>, ) -> Self

👎Deprecated since 0.4.0: Use with_validator() for validator nodes or with_fullnode() for full nodes instead

Add a new node using a nested NodeConfigBuilder.

Deprecated: Use [with_validator] for validator nodes or [with_fullnode] for full nodes instead.

pub fn with_node_group( self, f: impl FnOnce(GroupNodeConfigBuilder<Initial>) -> GroupNodeConfigBuilder<Buildable>, ) -> Self

Add a new group node using a nested GroupNodeConfigBuilder.

pub fn build(self) -> Result<RelaychainConfig, Vec<Error>>

Seals the builder and returns a RelaychainConfig if there are no validation errors, else returns errors.
