Module typed_bytes 

Typed byte newtypes for the Swarm protocol.

Mirrors bee-go’s pkg/swarm/typed_bytes.go (which itself mirrors bee-js’s src/utils/typed-bytes.ts). Each type is a length-validated wrapper over a fixed-size byte array; on the wire each is encoded as lowercase hex without 0x prefix.

Structs

BatchId

Postage batch identifier (32 bytes).

EthAddress

Ethereum address (20 bytes). EthAddress::to_checksum returns the EIP-55 mixed-case representation with 0x prefix.

FeedIndex

Feed index: 8 bytes, big-endian u64. The all-0xff value is a “before first” sentinel matching bee-js FeedIndex.MINUS_ONE.

Identifier

Arbitrary 32-byte identifier (SOC / GSOC). Use Identifier::from_string for the keccak256-of-utf8 variant.

PeerAddress

Peer overlay address (32 bytes).

Signature

Ethereum signed-message signature: R || S || V with V normalized to {27, 28} on the wire, matching bee-js.

Span

Chunk span: 8 bytes, little-endian u64.

Topic

Feed / PSS topic (32 bytes). Use Topic::from_string for the keccak256-of-utf8 variant.

TransactionId

Ethereum transaction hash (32 bytes).

Enums

Reference

Swarm content reference. 32 bytes for a plain CAC reference, 64 bytes for an encrypted reference (CAC address || encryption key).

Constants

BATCH_ID_LENGTH

Length of a postage batch identifier.

ENCRYPTED_REFERENCE_LENGTH

PRIVATE_KEY_LENGTH

Length of a secp256k1 private key.

PUBLIC_KEY_LENGTH

Length of a secp256k1 public key (uncompressed X || Y).

REFERENCE_LENGTH

Length of a plain content reference.

SIGNATURE_LENGTH

Length of an Ethereum signed-message signature (R || S || V).

SPAN_LENGTH

Length of a chunk span (little-endian u64).

TOPIC_LENGTH

Length of a feed / PSS topic.

TRANSACTION_ID_LENGTH

Length of a transaction hash.
