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.

Trait Implementations

impl Clone for TimeUnit

fn clone(&self) -> TimeUnit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TimeUnit

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

Formats the value using the given formatter.

impl Default for TimeUnit

fn default() -> TimeUnit

Returns the “default value” for a type.

impl Display for TimeUnit

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

Formats the value using the given formatter.

impl PartialEq for TimeUnit

fn eq(&self, other: &TimeUnit) -> 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 Copy for TimeUnit
