Enum Label 

pub enum Label {
    I64(i64),
    Str(String),
}

A single row-index label: an integer / datetime (I64, ns) or a string (Str). It decouples label lookup from the index’s storage so the same .loc / .at / .loc[a:b] / drop paths serve every index kind.

Variants

I64(i64)

An integer or datetime-ns label.

Str(String)

A string label.

pub fn as_i64(&self) -> Option<i64>
