Struct mz_repr::adt::datetime::DateTimeFieldValue

pub struct DateTimeFieldValue {
    pub unit: i64,
    pub fraction: i64,
}

Tracks a unit and a fraction from a parsed time-like string, e.g. INTERVAL ‘1.2’ DAYS.

Fields

unit: i64

Integer part of the value.

fraction: i64

Fractional part of value, padded to billions/has 9 digits of precision, e.g. .5 is represented as 500000000.

Implementations

impl DateTimeFieldValue

pub fn new(unit: i64, fraction: i64) -> Self

Construct DateTimeFieldValue { unit, fraction }.

const FRACTIONAL_DIGIT_PRECISION: i64 = 1_000_000_000i64

How much padding is added to the fractional portion to achieve a given precision. e.g. with the current precision .5 is represented as 500_000_000.

Trait Implementations

impl Clone for DateTimeFieldValue

fn clone(&self) -> DateTimeFieldValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DateTimeFieldValue

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

Formats the value using the given formatter.

impl Default for DateTimeFieldValue

fn default() -> Self

Returns the “default value” for a type.

impl Hash for DateTimeFieldValue

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 PartialEq<DateTimeFieldValue> for DateTimeFieldValue

fn eq(&self, other: &DateTimeFieldValue) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
