addSelfFetchFunctions<TData> function

SelfFetchFunctions<TData> addSelfFetchFunctions<TData>(Rpc rpc, Decoder<TData> decoder)

Augments a Decoder with self-fetch methods by wrapping it in a SelfFetchFunctions instance.

This enables a fluent API where you can call methods like .fetch() directly on the returned object to retrieve and decode accounts in one step.

Example:

final fetchable = addSelfFetchFunctions(rpc, myDecoder);

// Fetch and decode an account in one step.
final account = await fetchable.fetch(accountAddress);

// Handle accounts that may not exist.
final maybeAccount = await fetchable.fetchMaybe(accountAddress);
if (maybeAccount.exists) {
  // Use maybeAccount.
}

// Fetch multiple accounts at once (throws if any are missing).
final accounts = await fetchable.fetchAll([addressA, addressB]);

// Fetch multiple accounts, allowing some to be missing.
final maybeAccounts = await fetchable.fetchAllMaybe([addressA, addressB]);

Implementation

SelfFetchFunctions<TData> addSelfFetchFunctions<TData>(
  Rpc rpc,
  Decoder<TData> decoder,
) {
  return SelfFetchFunctions<TData>(decoder: decoder, rpc: rpc);
}
