Enum DateValue 

#[non_exhaustive]
pub enum DateValue {
    Specific(NaiveDate),
    Today,
    Yesterday,
    ThisWeek,
    ThisMonth,
    Relative {
        amount: u32,
        unit: RelativeUnit,
    },
}

Date value for QueryNode::DateRange.

The parser does not resolve Relative against a concrete now — that’s deliberate. A query parsed today and serialised back via Display must mean the same thing tomorrow. Backends resolve Relative against ParserOptions::now_provider when building an executable query.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Specific(NaiveDate)

Today

Yesterday

ThisWeek

ThisMonth

Relative

older_than:5d, newer_than:2w, etc. — a duration relative to “now”. Resolution happens at query-execution time.

Fields

amount: u32

unit: RelativeUnit

Trait Implementations

impl Clone for DateValue

fn clone(&self) -> DateValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DateValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DateValue

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DateValue

fn eq(&self, other: &DateValue) -> 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 DateValue

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for DateValue

impl StructuralPartialEq for DateValue
