Struct BlockchainExplorer

pub struct BlockchainExplorer<'a> { /* private fields */ }

Blockchain explorer.

Notes

The explorer wraps a specific Snapshot of the blockchain state; that is, all calls to the methods of an explorer instance are guaranteed to be consistent.

Implementations

impl<'a> BlockchainExplorer<'a>

pub fn new(snapshot: &'a dyn Snapshot) -> Self

Creates a new BlockchainExplorer instance from the provided snapshot.

pub fn from_schema(schema: Schema<&'a dyn Snapshot>) -> Self

Creates a new BlockchainExplorer instance from the core schema.

pub fn transaction(&self, tx_hash: &Hash) -> Option<TransactionInfo>

Returns information about the transaction identified by the hash.

pub fn call_status( &self, block_height: Height, call_location: CallInBlock, ) -> Result<(), ExecutionError>

Returns the status of a call in a block.

Return value

This method will return Ok(()) both if the call completed successfully, or if was not performed at all. The caller is responsible to distinguish these two outcomes.

pub fn transaction_without_proof( &self, tx_hash: &Hash, ) -> Option<Verified<AnyTx>>

Return transaction message without proof.

pub fn height(&self) -> Height

Return the height of the blockchain.

pub fn block(&self, height: Height) -> Option<BlockInfo<'_>>

Returns block information for the specified height or None if there is no such block.

pub fn block_with_txs(&self, height: Height) -> Option<BlockWithTransactions>

Return a block together with its transactions at the specified height, or None if there is no such block.

pub fn blocks<R: RangeBounds<Height>>(&self, heights: R) -> Blocks<'_>

Iterates over blocks in the blockchain.
