Module polkadot_node_primitives::approval::v2

A list of primitives introduced by v2.

Structs

• AssignmentCertV2
  A certification of assignment.
• BitIndex
  A bit index in Bitfield.
• Bitfield
  A read-only bitvec wrapper
• IndirectAssignmentCertV2
  An assignment criterion which refers to the candidate under which the assignment is relevant by block hash.
• IndirectSignedApprovalVoteV2
  A signed approval vote which references the candidate indirectly via the block.
• Slot
  Unit type wrapper that represents a slot.
• VrfPreOutput
  VRF pre-output type suitable for schnorrkel operations.
• VrfProof
  VRF proof type suitable for schnorrkel operations.
• VrfSignature
  VRF signature data
• VrfTranscript
  Transcript ready to be used for VRF related operations.

Enums

• ApprovalConversionError
  Errors that can occur when trying to convert to/from approvals v1/v2
• AssignmentCertKindV2
  Certificate is changed compared to AssignmentCertKind:
• AssignmentConversionError
  Errors that can occur when trying to convert to/from assignment v1/v2
• BitfieldError
  Errors that can occur when creating and manipulating bitfields.

Constants

• ASSIGNED_CORE_CONTEXT
  A static context associated with producing randomness for v2 multi-core assignments.
• CORE_RANDOMNESS_CONTEXT
  A static context associated with producing randomness for a core.
• RELAY_VRF_MODULO_CONTEXT
  A static context used for all relay-vrf-modulo VRFs for v2 multi-core assignments.

Traits

• AsBitIndex
  Helper trait to convert primitives to BitIndex.

Type Aliases

• CandidateBitfield
  A read-only, non-zero bitfield. Each 1 bit identifies a candidate by the bitfield bit index.
• CoreBitfield
  A bitfield of core assignments.
• Randomness
  Randomness type required by BABE operations.
