Implementations

§

impl<G, E, EHF> ChainSpec<G, E, EHF>

pub fn boot_nodes(&self) -> &[MultiaddrWithPeerId]

A list of bootnode addresses.

pub fn name(&self) -> &str

Spec name.

pub fn id(&self) -> &str

Spec id.

pub fn telemetry_endpoints(&self) -> &Option<TelemetryEndpoints>

Telemetry endpoints (if any)

pub fn protocol_id(&self) -> Option<&str>

Network protocol id.

pub fn fork_id(&self) -> Option<&str>

Optional network fork identifier.

pub fn properties(&self) -> Map<String, Value>

Additional loosly-typed properties of the chain.

Returns an empty JSON object if ‘properties’ not defined in config

pub fn add_boot_node(&mut self, addr: MultiaddrWithPeerId)

Add a bootnode to the list.

pub fn extensions(&self) -> &E

Returns a reference to the defined chain spec extensions.

pub fn extensions_mut(&mut self) -> &mut E

Returns a mutable reference to the defined chain spec extensions.

pub fn from_genesis<F>( name: &str, id: &str, chain_type: ChainType, constructor: F, boot_nodes: Vec<MultiaddrWithPeerId>, telemetry_endpoints: Option<TelemetryEndpoints>, protocol_id: Option<&str>, fork_id: Option<&str>, properties: Option<Map<String, Value>>, extensions: E, code: &[u8] ) -> ChainSpec<G, E, EHF>
where F: Fn() -> G + 'static + Send + Sync,

👎Deprecated: from_genesis is planned to be removed in May 2024. Use builder() instead.

Create hardcoded spec.

pub fn builder(code: &[u8], extensions: E) -> ChainSpecBuilder<G, E, EHF>

Provides a ChainSpec builder.
