Enum Sortedness

Source

pub enum Sortedness {
    Unknown,
    KnownUnsorted,
    Increasing,
    Decreasing,
    IncreasingNaFirst,
    DecreasingNaFirst,
}

Expand description

Sortedness hint for ALTREP vectors.

Variants§

§

Unknown

Unknown sortedness.

§

KnownUnsorted

Known to be unsorted.

This corresponds to KNOWN_UNSORTED in R.

§

Increasing

Sorted in increasing order (may have ties).

§

Decreasing

Sorted in decreasing order (may have ties).

§

IncreasingNaFirst

Sorted in increasing order, with NAs first.

This corresponds to SORTED_INCR_NA_1ST in R.

§

DecreasingNaFirst

Sorted in decreasing order, with NAs first.

This corresponds to SORTED_DECR_NA_1ST in R.
