Enum RowIndex

pub enum RowIndex {
    Int(Vec<usize>),
    Date(Vec<NaiveDate>),
    Range(Range<usize>),
}

Represents the different types of row indices a Frame can have.

Variants

Int(Vec<usize>)

Integer-based index (e.g., 0, 1, 2, …). Values must be unique.

Date(Vec<NaiveDate>)

Date-based index. Values must be unique. Order is preserved as given.

Range(Range<usize>)

Default range index (0..num_rows) used when no specific index is provided.

Implementations

impl RowIndex

pub fn len(&self) -> usize

Returns the number of elements in the index.

pub fn is_empty(&self) -> bool

Checks if the index is empty.

Trait Implementations

impl Clone for RowIndex

fn clone(&self) -> RowIndex

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RowIndex

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

Formats the value using the given formatter.

impl PartialEq for RowIndex

fn eq(&self, other: &RowIndex) -> 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.
