Struct Duration 

pub struct Duration<U: DurationUnitSpec>(/* private fields */);

Duration in the given unit.

Implementations

impl<U: DurationUnitSpec> Duration<U>

pub fn new(value: i64) -> Self

Construct a new duration from an i64 count in unit U.

pub fn value(&self) -> i64

Return the inner value.

pub fn into_value(self) -> i64

Consume and return the inner value.

Trait Implementations

impl<U: DurationUnitSpec> ArrowBinding for Duration<U>

where U::Arrow: ArrowPrimitiveType<Native = i64>,

type Builder = PrimitiveBuilder<<U as DurationUnitSpec>::Arrow>

Concrete Arrow builder type used for this Rust type.

type Array = PrimitiveArray<<U as DurationUnitSpec>::Arrow>

Concrete Arrow array type produced by finish.

fn data_type() -> DataType

The Arrow DataType corresponding to this Rust type.

fn new_builder(capacity: usize) -> Self::Builder

Create a new builder with an optional capacity hint.

fn append_value(b: &mut Self::Builder, v: &Self)

Append a non-null value to the builder.

fn append_null(b: &mut Self::Builder)

Append a null to the builder.

fn finish(b: Self::Builder) -> Self::Array

Finish the builder and produce a typed Arrow array.

fn estimated_bytes_per_value() -> usize

Estimated bytes per value for variable-length types (String, Binary, etc.). Returns 0 for fixed-size types. Used to pre-allocate buffer space.

impl<U: DurationUnitSpec + 'static> ArrowBindingView for Duration<U>

where U::Arrow: ArrowPrimitiveType<Native = i64>,

Available on crate feature views only.

type Array = PrimitiveArray<<U as DurationUnitSpec>::Arrow>

The Arrow array type this view reads from.

type View<'a> = Duration<U>

The borrowed view type returned when accessing array elements. For example: &'a str for StringArray, i64 for Int64Array.

fn get_view( array: &Self::Array, index: usize, ) -> Result<Self::View<'_>, ViewAccessError>

Extract a view at the given index from the array.

impl<U: Clone + DurationUnitSpec> Clone for Duration<U>

fn clone(&self) -> Duration<U>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<U: Debug + DurationUnitSpec> Debug for Duration<U>

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

Formats the value using the given formatter.

impl<U: Hash + DurationUnitSpec> Hash for Duration<U>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<U: Ord + DurationUnitSpec> Ord for Duration<U>

fn cmp(&self, other: &Duration<U>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<U: PartialEq + DurationUnitSpec> PartialEq for Duration<U>

fn eq(&self, other: &Duration<U>) -> 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<U: PartialOrd + DurationUnitSpec> PartialOrd for Duration<U>

fn partial_cmp(&self, other: &Duration<U>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
