Crate chia_peer 

chia-peer — DIG Chia light-client connectivity (dig-node seam 1)

A thin wrapper that CONFIGURES and DRIVES chia_wallet_sdk’s light-client Peer so a DIG node can act as a Chia wallet-protocol client: connect to full nodes, subscribe to coin/puzzle-hash state, track the peak, handle reorgs, and submit spend bundles.

The heavy lifting — the wallet-protocol wire, TLS, DNS-introducer discovery, coin-state subscription, and transaction submission — lives in the SDK. This crate adds only DIG glue: IPv6-first dialing (§5.2), a reorg-aware subscription cache, reconnect-with-re-arm, and a ChainSource read facade.

Shape

• ChiaLightClient — connect, subscribe_coins, subscribe_puzzle_hashes, submit_spend, peak, unsubscribe_coins, reconnect, and as_chain_source_provider.
• ChiaPeerProvider — the synchronous, fail-closed ChainSource provider dig-node registers.

Reads are fail-closed

Through the provider, Ok(None)/empty means the peer reliably reported absence; any transport/subscription-gap failure is an Err, never a false Ok(None) — the crux of the dig_chainsource_interface contract.

The SDK version pairing

This crate pins chia-wallet-sdk = 0.30, which shares chia-protocol = 0.26 with dig-chainsource-interface. That single chia-protocol version is REQUIRED: a newer SDK pulls a newer chia-protocol whose types would not unify with the interface the provider implements.

Structs

ChiaLightClient

A connected Chia wallet-protocol light client.

ChiaPeerConfig

Connection + trust configuration for a ChiaLightClient.

ChiaPeerProvider

A ChainSource provider backed by a subscribing Chia light client.

PeerFetcher

A CoinStateFetcher backed by a live wallet-protocol Peer.

ProviderInfo

The self-description a provider hands the registry when it registers.

Enums

ChainSourceError

The reason a ChainSource could not reliably answer a read.

ChiaNetwork

The Chia network a client speaks to.

ChiaPeerError

The reason a Chia light-client peer read could not complete reliably.

ProviderKind

The category of a chain-source provider, so the registry can order and trust-weight providers.

SubmitOutcome

The outcome of submitting a spend bundle, mapped from the node’s TransactionAck status byte.

Constants

DEFAULT_PROVIDER_PRIORITY

The default try-order priority a chia-peer provider registers with (lower = tried earlier).

VERSION

The crate version, sourced from Cargo.toml at build time.

Traits

ChainSource

A reads-only view of Chia chain state — the single canonical contract every provider implements and every consumer depends on.

ChainSourceProvider

A ChainSource that describes itself to the aggregating registry.

CoinStateFetcher

The reads a provider issues against a Chia full node when its local cache misses.
