Implementations

impl Chain

pub fn chain_type(&self) -> ChainType

Get the chain type

pub fn name(&self) -> &str

Get the chain name

pub fn default_endpoint(&self) -> &str

Get default RPC endpoint for the chain

pub fn rpc_endpoints(&self) -> Vec<&str>

Get multiple RPC endpoints for reliability and failover

pub fn is_layer2(&self) -> bool

Check if chain is a Layer 2 solution

pub fn supports_smart_contracts(&self) -> bool

Check if chain supports smart contracts

pub fn is_testnet(&self) -> bool

Check if this is a testnet

pub fn from_str_case_insensitive(s: &str) -> Option<Chain>

Parse chain from string (case-insensitive)

pub fn is_substrate_endpoint(endpoint: &str) -> bool

Check if an endpoint URL is for Substrate (WebSocket-based)

pub fn is_evm_endpoint(endpoint: &str) -> bool

Check if an endpoint URL is for EVM (HTTP-based)

pub fn chain_id(&self) -> Option<u64>

Get the chain ID for EVM-compatible chains

Returns None for pure Substrate chains that don’t have a chain ID concept. For EVM and Hybrid chains, returns the standard EIP-155 chain ID.

pub fn validate_chain_id(&self, chain_id: u64) -> Result<(), ValidationError>

Validate that a given chain ID matches this chain

Returns an error if the chain ID doesn’t match the expected value. For Substrate-only chains, returns an error indicating chain ID is not applicable.

Trait Implementations

impl Clone for Chain

fn clone(&self) -> Chain

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Chain

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Chain

fn deserialize<__D>( __deserializer: __D, ) -> Result<Chain, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Chain

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Chain

fn eq(&self, other: &Chain) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Chain

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Chain

impl StructuralPartialEq for Chain
