Enum IndexKind 

pub enum IndexKind {
    Range(usize),
    Int64(Vec<i64>),
    Datetime(Vec<i64>, Tz),
    Str(Vec<String>),
}

The label storage backing an Index.

Defaults to an implicit 0..n range; a Datetime kind is the common OHLCV case (i64 nanoseconds since the Unix epoch); a Str kind (pandas object/string index) supports symbol-keyed lookup.

Variants

Range(usize)

Implicit 0..n integer labels.

Int64(Vec<i64>)

Explicit integer labels.

Datetime(Vec<i64>, Tz)

Datetime labels as i64 nanoseconds since the Unix epoch, with a display / matching timezone (UTC by default).

Str(Vec<String>)

String labels (pandas object/string index).

Trait Implementations

impl Clone for IndexKind

fn clone(&self) -> IndexKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndexKind

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

Formats the value using the given formatter.

impl PartialEq for IndexKind

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