Enum TimeUnit 

pub enum TimeUnit {
    Seconds,
    Milliseconds,
    Microseconds,
    Nanoseconds,
    Days,
}

TimeUnit

Unified time unit enumeration.

Purpose

• Combines time units for both DatetimeArray32 and DatetimeArray64.
• Confirm time since epoch units, or a raw duration value (depending on the ArrowType that’s attached to Field during FieldArray construction).
• Avoids proliferating variants that require explicit handling throughout match statements.

Behaviour

• Unit values are stored on the DatetimeArray, enabling variant-specific logic.
• When transmitted over FFI, an Apache Arrow- produces compatible native format.

Variants

Seconds

Seconds for Apache Arrow Time32 and Time64 units.

Milliseconds

Milliseconds for Apache Arrow Time32 and Time64 units.

Microseconds

Microseconds for Apache Arrow Time32 and Time64 units.

Nanoseconds

Nanoseconds for Apache Arrow Time32 and Time64 units.

Days

Default = days unspecified

Apache Arrow’s Date32 and Date64 types use days implicitly.
