Struct ChiaQueryProvider 

pub struct ChiaQueryProvider { /* private fields */ }

A ChainSource provider backed by chia-query’s async peer+coinset router.

Cloning shares the underlying ChiaQuery and runtime handle.

Implementations

impl ChiaQueryProvider

pub fn new(inner: Arc<ChiaQuery>, handle: Handle, info: ProviderInfo) -> Self

Builds a provider over inner, driving its async reads on handle (which MUST belong to a multi-thread runtime — see the module docs), and describing itself with info.

Trait Implementations

impl ChainSource for ChiaQueryProvider

type Error = ChainSourceError

The source’s own transport/parse error. crate::ChainSourceError is the recommended type for registry participants, but any Display error is accepted.

fn coin_record( &self, coin_id: Bytes32, ) -> Result<Option<CoinRecord>, Self::Error>

Reads the coin with id coin_id.

fn coin_records_by_puzzle_hash( &self, puzzle_hash: Bytes32, include_spent: bool, ) -> Result<Vec<CoinRecord>, Self::Error>

Reads all coins paying to puzzle_hash, optionally including already-spent coins.

fn coin_records_by_parent( &self, parent_coin_id: Bytes32, ) -> Result<Vec<CoinRecord>, Self::Error>

Reads all coins whose parent is parent_coin_id — the direct children created by spending that coin.

fn coin_spend(&self, coin_id: Bytes32) -> Result<Option<CoinSpend>, Self::Error>

Reads the spend that SPENT coin_id (the spend whose input coin is coin_id).

fn resolve_singleton_lineage( &self, launcher_id: Bytes32, ) -> Result<Option<SingletonLineage>, Self::Error>

Resolves the singleton launched at launcher_id to its authenticated SingletonLineage (every coin id from launcher to current tip).

fn peak_height(&self) -> Result<Option<u32>, Self::Error>

Reads the current peak (fully-synced) block height, if the source tracks one.

fn block_timestamp(&self, height: u32) -> Result<Option<u64>, Self::Error>

Reads the Unix timestamp of the block at height.

fn parent_spend( &self, coin_id: BytesImpl<32>, ) -> Result<Option<CoinSpend>, Self::Error>

Reads the spend that CREATED coin_id — i.e. the spend of coin_id’s parent — by resolving the coin’s parent and reading that parent’s spend. This is the money-critical parent-walk primitive.

impl ChainSourceProvider for ChiaQueryProvider

fn provider_info(&self) -> ProviderInfo

This provider’s registration descriptor (identity, kind, priority, trust posture).

impl Clone for ChiaQueryProvider

fn clone(&self) -> ChiaQueryProvider

Returns a duplicate of the value.

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

Performs copy-assignment from source.
