Module fvm_shared::commcid

Constants

• FIL_COMMITMENT_SEALED
• FIL_COMMITMENT_UNSEALED
• POSEIDON_BLS12_381_A1_FC1
  Multihash code for Poseidon BLS replica commitments.
• SHA2_256_TRUNC254_PADDED
  Multihash code for Sha2 256 trunc254 padded used in data commitments.

Functions

• cid_to_commitment
  CIDToCommitment extracts the raw commitment bytes, the FilMultiCodec and FilMultiHash from a CID, after validating that the codec and hash type are consistent
• cid_to_data_commitment_v1
  cid_to_data_commitment_v1 extracts the raw data commitment from a CID assuming that it has the correct hashing function and serialization types
• cid_to_piece_commitment_v1
  cid_to_piece_commitment_v1 converts a CID to a comm_p – it is just a helper function that is equivalent to cid_to_data_commitment_v1.
• cid_to_replica_commitment_v1
  cid_to_replica_commitment_v1 extracts the raw replica commitment from a CID assuming that it has the correct hashing function and serialization types
• commitment_to_cid
  CommitmentToCID converts a raw commitment hash to a CID by adding:
• data_commitment_v1_to_cid
  DataCommitmentV1ToCID converts a raw data commitment to a CID by adding:
• piece_commitment_v1_to_cid
  piece_commitment_v1_to_cid converts a comm_p to a CID – it is just a helper function that is equivalent to data_commitment_v1_to_cid.
• replica_commitment_v1_to_cid
  ReplicaCommitmentV1ToCID converts a raw data commitment to a CID by adding:
