Struct sql_parser::ast::defs::value::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 Clone for IntervalValue

fn clone(&self) -> IntervalValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IntervalValue

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

Formats the value using the given formatter.

impl Default for IntervalValue

fn default() -> Self

Returns the “default value” for a type.

impl Hash for IntervalValue

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, 

Feeds a slice of this type into the given Hasher.
