Modules

config

Exonum blockchain configuration.

Structs

AdditionalHeaders	Expandable set of headers allowed to be added to the block.
ApiSender	Asynchronous sender of messages (transactions by default). The receiver of messages is usually an Exonum node, which then processes them with the consensus algorithm.
Block	Header of a block.
BlockParams	Block metadata provided to `BlockchainMut::create_patch` by the consensus algorithm.
BlockPatch	Opaque database patch corresponding to a block of transactions.
BlockProof	Block with its `Precommit` messages.
Blockchain	Shared Exonum blockchain instance.
BlockchainBuilder	The object responsible for the correct Exonum blockchain creation from the components.
BlockchainMut	Mutable blockchain capable of processing transactions.
CallErrorsIter	Iterator over errors in a block returned by `CallRecords::errors()`.
CallProof	Proof of authenticity for a single top-level call in a block, such as a transaction.
CallRecords	Information about call errors within a specific block.
Epoch	Epoch of the consensus algorithm. This field must be present in all correctly formed blocks.
IndexProof	Proof of authenticity for a single index within the database.
PersistentPool	Persistent transaction pool that uses both a provided ephemeral cache and the cache persisting in the node database.
ProposerId	Identifier of a proposer of the block.
Schema	Information schema for indexes maintained by the Exonum core logic.
SendError	Errors that can occur during sending a message to the node via `ApiSender`.
SkipFlag	Flag indicating a block skip. This flag is not set for normal blocks.
TxLocation	Transaction location in a block. Defines the block where the transaction was included and the position of this transaction in the block.

Enums

BlockContents	Contents of a block, defining how the block is applied to the blockchain state.
BlockKind	Block kind, acting as an abridged version of `BlockContents`.
CallInBlock	Location of an isolated call within a block.
ProofError	Errors that can occur during verification of `BlockProof`s, `IndexProof`s and `CallProof`s.

Traits

BlockHeaderKey	Trait that represents a key in block header entry map. Provides a mapping between `NAME` of the entry and its value.
TransactionCache	Container for transactions allowing to look them up by hash digest.

Type Definitions

Transactions

Iterator type for transactions in TransactionCache.
