Enum IntervalUnitSpec 

pub enum IntervalUnitSpec {
    Simple {
        unit: IntervalUnit,
        use_plural: bool,
    },
    Span(IntervalSpan),
    ExprSpan(IntervalSpanExpr),
    Expr(Box<Expression>),
}

Specification for interval unit - can be a simple unit, a span (HOUR TO SECOND), or an expression

Variants

Simple

Simple interval unit (YEAR, MONTH, DAY, etc.)

Fields

unit: IntervalUnit

use_plural: bool

Whether to use plural form (e.g., DAYS vs DAY)

Span(IntervalSpan)

Interval span (e.g., HOUR TO SECOND)

ExprSpan(IntervalSpanExpr)

Expression-based interval span for Oracle (e.g., DAY(9) TO SECOND(3)) The start and end can be expressions like function calls with precision

Expr(Box<Expression>)

Expression as unit (e.g., CURRENT_DATE, CAST(GETDATE() AS DATE))

Trait Implementations

impl Clone for IntervalUnitSpec

fn clone(&self) -> IntervalUnitSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IntervalUnitSpec

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for IntervalUnitSpec

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for IntervalUnitSpec

fn eq(&self, other: &IntervalUnitSpec) -> 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 Serialize for IntervalUnitSpec

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
