Enum RowSegmentSource 

pub enum RowSegmentSource {
    Contiguous {
        start: usize,
        len: usize,
    },
    Wrapped {
        start: usize,
        len: usize,
    },
    Indexed,
}

How a RowSegment was extracted from its source row.

Variants

Contiguous

A contiguous slice [start, start + len).

Fields

start: usize

Zero-based ordinal at which the segment starts.

len: usize

Number of row positions included.

Wrapped

A wrapping slice starting at start and continuing modulo twelve.

Fields

start: usize

Zero-based ordinal at which the wrapped segment starts.

len: usize

Number of row positions included.

Indexed

An explicit ordinal sequence.
