Module casper_node::types

Common types used across multiple components.

Re-exports

• pub use chainspec::Chainspec;
• pub use error::BlockValidationError;
• pub use peers_map::PeersMap;

Modules

• chainspec
  The chainspec is a set of configuration options for the network. All validators must apply the same set of options in order to join and act as a peer in a given network.
• error
  Errors that may be emitted by methods for common types.
• json_compatibility
  Types which are serializable to JSON, which map to types defined outside this module.
• peers_map
  Peers map.

Structs

• Approval
  A struct containing a signature of a deploy hash and the public key of the signer.
• ApprovalsHash
  The cryptographic hash of the bytesrepr-encoded set of approvals for a single deploy.
• AvailableBlockRange
  An unbroken, inclusive range of blocks.
• Block
  A proposed block after execution, with the resulting post-state-hash. This is the core component of the Casper linear blockchain.
• BlockAndDeploys
  Wrapper around block and its deploys.
• BlockBody
  The body portion of a block.
• BlockExecutionResultsOrChunk
  Represents execution results for all deploys in a single block or a chunk of this complete value.
• BlockExecutionResultsOrChunkId
  ID of the request for block execution results or chunk.
• BlockExecutionResultsOrChunkIdDisplay
  Helper struct to on-demand deserialize a trie or chunk ID for display purposes.
• BlockHash
  A cryptographic hash identifying a Block.
• BlockHeader
  The header portion of a Block.
• BlockSignatures
  A storage representation of finality signatures with the associated block hash.
• ChainspecInfo
  Summary information from the chainspec.
• Deploy
  A deploy; an item containing a smart contract along with the requester’s signature(s).
• DeployHash
  The cryptographic hash of a Deploy.
• DeployHeader
  The header portion of a Deploy.
• ExcessiveSizeDeployError
  Error returned when a Deploy is too large.
• FinalitySignature
  A validator’s signature of a block, to confirm it is finalized. Clients and joining nodes should wait until the signers’ combined weight exceeds their fault tolerance threshold before accepting the block as finalized.
• FinalizedBlock
  The piece of information that will become the content of a future block after it was finalized and before execution happened yet.
• GetStatusResult
  Result for “info_get_status” RPC response.
• JsonBlock
  A JSON-friendly representation of Block.
• JsonBlockHeader
  JSON representation of a block header.
• NodeConfig
  Node fast-sync configuration.
• StatusFeed
  Data feed for client “info_get_status” endpoint.
• TrieOrChunkId
  Represents the ID of a TrieOrChunk - containing the index and the root hash. The root hash is the hash of the trie node as a whole. The index is the index of a chunk if the node’s size is too large and requires chunking. For small nodes, it’s always 0.
• TrieOrChunkIdDisplay
  Helper struct to on-demand deserialize a trie or chunk ID for display purposes.

Enums

• ChunkingError
  Error returned when constructing an instance of ValueOrChunk.
• DeployConfigurationFailure
  A representation of the way in which a deploy failed validation checks.
• DeployError
  Errors other than validation failures relating to Deploys.
• DeployOrTransferHash
  The DeployHash stored in a way distinguishing between Wasm deploys and transfers.
• ExitCode
  Exit codes which should be used by the casper-node binary, and provided by the reactor to the binary.
• SyncHandling
  Node sync configuration.
• ValueOrChunk
  Represents a value or a chunk of data with attached proof.

Traits

• Chunkable
  Implemented for types that are chunked when sending over the wire and/or before storing the trie store.
• CryptoRngCore
  An object-safe RNG trait that requires a cryptographically strong random number generator.
• DataSize
  Indicates that a type knows how to approximate its memory usage.

Type Aliases

• NodeRng
  The cryptographically secure RNG used throughout the node.
• TrieOrChunk
  Represents an enum that can contain either a whole trie or a chunk of it.

Derive Macros

• DataSize
  Automatically derive the DataSize trait for a type.
