Crate polkadot_node_primitives

Expand description

Primitive types used on the node-side.

Unlike the polkadot-primitives crate, these primitives are only used on the node-side, not shared between the node and the runtime. This crate builds on top of the primitives defined there.

Re-exports§

pub use disputes::dispute_is_inactive;
pub use disputes::CandidateVotes;
pub use disputes::DisputeMessage;
pub use disputes::DisputeMessageCheckError;
pub use disputes::DisputeStatus;
pub use disputes::InvalidDisputeVote;
pub use disputes::SignedDisputeStatement;
pub use disputes::Timestamp;
pub use disputes::UncheckedDisputeMessage;
pub use disputes::ValidDisputeVote;
pub use disputes::ACTIVE_DURATION_SECS;

Modules§

approval: Types relevant for approval.
disputes: Disputes related types.

Macros§

new_session_window_size: Create a new checked SessionWindowSize which cannot be 0.

Structs§

AvailableData: This is the data we keep available for each candidate included in the relay chain.
BabeEpoch: BABE epoch information
BabeEpochConfiguration: Configuration data used by the BABE consensus engine that may change with epochs.
BlockData: Parachain block data.
Collation: The output of a collator.
CollationGenerationConfig: Configuration for the collation generator
CollationResult: Result of the CollatorFn invocation.
CollationSecondedSignal: Signal that is being returned when a collation was seconded by a validator.
ErasureChunk: A chunk of erasure-encoded block data.
PoV: A Proof-of-Validity
Proof: This is a convenience type to allow the Erasure chunk proof to Decode into a nested BoundedVec
SessionWindowSize: Type of a session window size.
SubmitCollationParams: Parameters for CollationGenerationMessage::SubmitCollation.

Enums§

BabeAllowedSlots: Types of allowed slots.
InvalidCandidate: Candidate invalidity details
MaybeCompressedPoV: A type that represents a maybe compressed PoV.
MerkleProofError: Possible errors when converting from Vec<Vec<u8>> into Proof.
Statement: A statement, where the candidate receipt is included in the Seconded variant.
StatementWithPVD: A statement, exactly the same as Statement but where seconded messages carry the PersistedValidationData.
ValidationResult: Result of the validation of the candidate.

Constants§

DISPUTE_CANDIDATE_LIFETIME_AFTER_FINALIZATION: How many blocks after finalization an information about backed/included candidate should be pre-loaded (when scraping onchain votes) and kept locally (when pruning).
DISPUTE_WINDOW: It would be nice to draw this from the chain state, but we have no tools for it right now. On Polkadot this is 1 day, and on Kusama it’s 6 hours.
MAX_FINALITY_LAG: Linked to MAX_FINALITY_LAG in relay chain selection, MAX_HEADS_LOOK_BACK in approval-voting and MAX_BATCH_SCRAPE_ANCESTORS in dispute-coordinator
NODE_VERSION: The current node version, which takes the basic SemVer form <major>.<minor>.<patch>. In general, minor should be bumped on every release while major or patch releases are relatively rare.
POV_BOMB_LIMIT: The bomb limit for decompressing PoV blobs.
VALIDATION_CODE_BOMB_LIMITDeprecated: The bomb limit for decompressing code blobs.

Functions§

maybe_compress_pov: Compress a PoV, unless it exceeds the POV_BOMB_LIMIT.

Type Aliases§

BabeRandomness: Randomness type required by BABE operations.
BlockWeight: The cumulative weight of a block in a fork-choice rule.
CollatorFn: Collation function.
HorizontalMessages
SignedFullStatement: A statement, the corresponding signature, and the index of the sender.
SignedFullStatementWithPVD: A statement, the corresponding signature, and the index of the sender.
UncheckedSignedFullStatement: Variant of SignedFullStatement where the signature has not yet been verified.
