def frame_has_minimal_ranks(
        shape:          typ.Sequence[int],
        up_ranks:       typ.Sequence[int],
        down_ranks:     typ.Sequence[int],
        left_ranks:     typ.Sequence[int],
        right_ranks:    typ.Sequence[int],
) -> bool:

True if a T3Frame with these (redundant) ranks is structurally minimal.

Requires the left/right and up/down rank stores to agree, and the up/left ranks to equal the minimal ranks for the shape.

Parameters:

• shape (t3toolbox.backend.common.typ.Sequence[int])

• up_ranks (t3toolbox.backend.common.typ.Sequence[int])

• down_ranks (t3toolbox.backend.common.typ.Sequence[int])

• left_ranks (t3toolbox.backend.common.typ.Sequence[int])

• right_ranks (t3toolbox.backend.common.typ.Sequence[int])

Return type:

bool
