jam.state.components.theta module

class jam.state.components.theta.ReadyWR(report: jam.types.work.report.WorkReport, dependencies: jam.types.base.sequences.bytes.byte_array.ByteArray32)

Bases: Codable

report: WorkReport

dependencies: ByteArray32

__init__(report: WorkReport, dependencies: ByteArray32) → None

Initialize the Codable.

Parameters:

• codec – Optional codec to use for encoding/decoding

• enc_sequence – Optional function that returns sequence of fields to encode

static decode_from(buffer: bytes | bytearray | memoryview, offset: int = 0) → Tuple[T, int]

Decode from buffer. Must be implemented by subclasses or added via decorator.

Parameters:

• buffer – Buffer to decode from

• offset – Starting position in buffer

Returns:

• The decoded value

• Number of bytes read

Return type:

Tuple containing

encode_into(buffer: bytearray, offset: int = 0) → int

Encode into provided buffer.

encode_size() → int

Calculate number of bytes needed to encode.
