Struct Date

pub struct Date { /* private fields */ }

Date in the proleptic Gregorian calendar.

By default, years between ±9999 inclusive are representable. This can be expanded to ±999,999 inclusive by enabling the large-dates crate feature. Doing so has performance implications and introduces some ambiguities when parsing.

impl PgHasArrayType for Date

fn array_type_info() -> PgTypeInfo

fn array_compatible(ty: &PgTypeInfo) -> bool

impl SmartDisplay for Date

type Metadata = DateMetadata

User-provided metadata type.

fn metadata(&self, _: FormatterOptions) -> Metadata<'_, Date>

Compute any information needed to format the value. This must, at a minimum, determine the width of the value before any padding is added by the formatter.

fn fmt_with_metadata( &self, f: &mut Formatter<'_>, metadata: Metadata<'_, Date>, ) -> Result<(), Error>

Format the value using the given formatter and metadata. The formatted output should have the width indicated by the metadata. This is before any padding is added by the formatter.

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

Format the value using the given formatter. This is the same as Display::fmt.
