Struct mz_sql::ast::IntervalValue

pub struct IntervalValue {
    pub value: String,
    pub precision_high: DateTimeField,
    pub precision_low: DateTimeField,
    pub fsec_max_precision: Option<u64>,
}

An intermediate value for Intervals, which tracks all data from the user, as well as the computed ParsedDateTime.

Fields

value: String

The raw [value] that was present in INTERVAL '[value]'

precision_high: DateTimeField

The most significant DateTimeField to propagate to Interval in compute_interval.

precision_low: DateTimeField

The least significant DateTimeField to propagate to Interval in compute_interval. precision_low is also used to provide a TimeUnit if the final part of value is ambiguous, e.g. INTERVAL ‘1-2 3’ DAY uses ‘day’ as the TimeUnit for 3.

fsec_max_precision: Option<u64>

Maximum nanosecond precision can be specified in SQL source as INTERVAL '__' SECOND(_).

Trait Implementations

impl Default for IntervalValue

fn default() -> IntervalValue

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for IntervalValue

fn deserialize<__D>( __deserializer: __D, ) -> Result<IntervalValue, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

impl Ord for IntervalValue

fn cmp(&self, other: &IntervalValue) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for IntervalValue

fn eq(&self, other: &IntervalValue) -> 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.

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.

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,
