Struct ChainRegistry 

Source 
pub struct ChainRegistry<P>(/* private fields */);
Expand description

Registry of configured chain providers indexed by chain ID.

§Type Parameters

  • P - The chain provider type (e.g., Eip155ChainProvider or SolanaChainProvider)

Implementations§

Source§

impl<P> ChainRegistry<P>

Source

pub const fn new(providers: HashMap<ChainId, P>) -> Self

Creates a new registry from the given provider map.

Source§

impl<P> ChainRegistry<P>

Source

pub fn by_chain_id(&self, chain_id: &ChainId) -> Option<&P>

Looks up a provider by exact chain ID.

Returns None if no provider is configured for the given chain.

Source

pub fn by_chain_id_pattern(&self, pattern: &ChainIdPattern) -> Vec<&P>

Looks up providers by chain ID pattern matching.

Returns all providers whose chain IDs match the given pattern. The pattern can be:

  • Wildcard: Matches any chain within a namespace (e.g., eip155:*)
  • Exact: Matches a specific chain (e.g., eip155:8453)
  • Set: Matches any chain from a set of references (e.g., eip155:{1,8453,137})
