Expand description

Primitive types which are strictly necessary from a parachain-execution point of view.

Structs§

  • BlockData
    Parachain block data.
  • HeadData
    Parachain head data included in the chain.
  • HrmpChannelId
    A type that uniquely identifies an HRMP channel. An HRMP channel is established between two paras. In text, we use the notation (A, B) to specify a channel between A and B. The channels are unidirectional, meaning that (A, B) and (B, A) refer to different channels. The convention is that we use the first item tuple for the sender and the second for the recipient. Only one channel is allowed between two participants in one direction, i.e. there cannot be 2 different channels identified by (A, B). A channel with the same para id in sender and recipient is invalid. That is, however, not enforced.
  • Id
    Unique identifier of a parachain.
  • Sibling
  • ValidationCode
    Parachain validation code.
  • ValidationCodeHash
    Unit type wrapper around Hash that represents the blake2-256 hash of validation code in particular.
  • ValidationParams
    Validation parameters for evaluating the parachain validity function.
  • ValidationResult
    The result of parachain validation.
