Struct RelaychainConfigBuilder

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

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

Implementations

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_chain_spec_command(self, cmd_template: impl Into<String>) -> Self

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

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_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_node( self, f: impl FnOnce(NodeConfigBuilder<Initial>) -> NodeConfigBuilder<Buildable>, ) -> RelaychainConfigBuilder<WithAtLeastOneNode>

Add a new node using a nested NodeConfigBuilder.

impl RelaychainConfigBuilder<WithAtLeastOneNode>

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

Add a new node using a nested NodeConfigBuilder.

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

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

Trait Implementations

impl Default for RelaychainConfigBuilder<Initial>

fn default() -> Self

Returns the “default value” for a type.
