class jam.state.components.psi.PsiG(initial: Sequence[T] = [], codec: Codec[T] | None = None)[source]

Bases: Vector[ByteArray32]

Good set work report hashes

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