Static Methods

decode(Uint8List payload, void visit(WalOpKind kind, Uint8List key, Uint8List? value)) → void

Decodes a frame payload, visiting operations in order.

encode(List<WalOp> ops) → Uint8List

Encodes ops into a frame payload.

encodedSize(List<WalOp> ops) → int

Bytes needed to encode ops.

encodeInto(Uint8List out, int offset, List<WalOp> ops) → int

Encodes ops into out starting at offset; returns the end offset.

opSize(Uint8List key, Uint8List? value) → int

Bytes needed for one operation, excluding the batch count.

writeOp(Uint8List out, int offset, WalOpKind kind, Uint8List key, Uint8List? value) → int

Writes one operation and returns the end offset.
