Struct diesel::pg::data_types::PgDate

pub struct PgDate(pub i32);

Available on crate feature postgres_backend only.

Dates are represented in Postgres as a 32 bit signed integer representing the number of julian days since January 1st 2000. This struct is a dumb wrapper type, meant only to indicate the integer’s meaning.

Trait Implementations

impl Arbitrary for PgDate

Available on crate feature quickcheck only.

The expression being returned

fn as_expression(self) -> Self::Expression

Perform the conversion

impl AsExpression<Nullable<Date>> for PgDate

type Expression = Bound<Nullable<Date>, PgDate>

The expression being returned

fn as_expression(self) -> Self::Expression

Perform the conversion

impl Clone for PgDate

fn clone(&self) -> PgDate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PgDate

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

Formats the value using the given formatter.

impl FromSql<Date, Pg> for PgDate

fn from_sql(bytes: PgValue<'_>) -> Result<Self>

See the trait documentation.

fn from_nullable_sql(bytes: Option<DB::RawValue<'_>>) -> Result<Self>

A specialized variant of from_sql for handling null values.

impl Ord for PgDate

fn cmp(&self, other: &PgDate) -> 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 PgDate

fn eq(&self, other: &PgDate) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for PgDate

fn partial_cmp(&self, other: &PgDate) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl<__ST, __DB> Queryable<__ST, __DB> for PgDate

where __DB: Backend, __ST: SingleValue, Self: FromSql<__ST, __DB>,

type Row = PgDate

The Rust type you’d like to map from.

fn build(row: Self::Row) -> Result<Self>

Construct an instance of this type

impl ToSql<Date, Pg> for PgDate

fn to_sql<'b>(&'b self, out: &mut Output<'b, '_, Pg>) -> Result

See the trait documentation.

impl<__DB> ToSql<Nullable<Date>, __DB> for PgDate

where __DB: Backend, Self: ToSql<Date, __DB>,

fn to_sql<'__b>(&'__b self, out: &mut Output<'__b, '_, __DB>) -> Result

See the trait documentation.
