Enum Sortedness 

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

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.

Implementations

impl Sortedness

pub fn to_r_int(self) -> i32

Convert to R’s integer representation.

pub fn from_r_int(i: i32) -> Self

Convert from R’s integer representation.

Trait Implementations

impl Clone for Sortedness

fn clone(&self) -> Sortedness

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Sortedness

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Sortedness> for i32

Convert Sortedness to R’s integer representation.

fn from(s: Sortedness) -> i32

Converts to this type from the input type.

impl From<i32> for Sortedness

Convert R’s integer sortedness code to Sortedness.

fn from(i: i32) -> Self

Converts to this type from the input type.

impl PartialEq for Sortedness

fn eq(&self, other: &Sortedness) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Sortedness

impl Eq for Sortedness
