Enum r::object::Subset

pub enum Subset {
    Indices(CowObj<Vec<Integer>>),
    Mask(CowObj<Vec<Logical>>),
    Names(CowObj<Vec<Character>>),
    Range(Range<usize>),
}

Subsets

Representations of how data views might be specified. Indices are 0-indexed, for direct use against rust-internal representations.

Variants

Indices(CowObj<Vec<Integer>>)

Mask(CowObj<Vec<Logical>>)

Names(CowObj<Vec<Character>>)

Range(Range<usize>)

Trait Implementations

impl Clone for Subset

fn clone(&self) -> Subset

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Subset

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

Formats the value using the given formatter.

impl From<Range<usize>> for Subset

fn from(value: Range<usize>) -> Self

Converts to this type from the input type.

impl From<Vec<usize>> for Subset

fn from(value: Vec<usize>) -> Self

Converts to this type from the input type.

impl From<usize> for Subset

fn from(value: usize) -> Self

Converts to this type from the input type.

impl PartialEq for Subset

fn eq(&self, other: &Subset) -> 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 TryFrom<Obj> for Subset

type Error = Signal

The type returned in the event of a conversion error.

fn try_from(value: Obj) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Vector> for Subset

type Error = Signal

The type returned in the event of a conversion error.

fn try_from(value: Vector) -> Result<Self, Self::Error>

Performs the conversion.

impl StructuralPartialEq for Subset
