Field Paths

Decodes Huffman-coded field path operations used to address properties inside entity deltas.

Generated API

def read_field_paths(r: BitReader) -> list[FieldPath]

Decode field paths into independent mutable compatibility objects.

class FieldPath

A mutable path of up to 7 integer field indices.

Signature: def FieldPath.reset(self) -> None

Reset to the initial empty state.

Signature: def FieldPath.pop(self, n: int) -> None

Pop n levels off the path, zeroing the vacated slots.

Signature: def FieldPath.copy(self) -> FieldPath

Return an independent copy of this path.

Signature: def FieldPath.to_tuple(self) -> CompactFieldPath

Return the active indices as an immutable tuple.

Signature: def FieldPath.to_str(self) -> str

Return a slash-separated string of active indices.

Signature: def FieldPath.plus_one(self) -> None

Increment the deepest index by 1.

class FieldPathOp

A single field-path operation with its Huffman weight.

Name	Type	Default
