Enum tokio_postgres::types::Date

pub enum Date<T> {
    PosInfinity,
    NegInfinity,
    Value(T),
}

A wrapper that can be used to represent infinity with Type::Date types.

Variants

PosInfinity

Represents infinity, a date that is later than all other dates.

NegInfinity

Represents -infinity, a date that is earlier than all other dates.

Value(T)

The wrapped date.

Trait Implementations

impl<T> Clone for Date<T>where T: Clone,

fn clone(&self) -> Date<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Date<T>where T: Debug,

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

Formats the value using the given formatter.

impl<'a, T> FromSql<'a> for Date<T>where T: FromSql<'a>,

fn from_sql( ty: &Type, raw: &'a [u8] ) -> Result<Date<T>, Box<dyn Error + Sync + Send, Global>>

Creates a new value of this type from a buffer of data of the specified Postgres Type in its binary format.

fn accepts(ty: &Type) -> bool

Determines if a value of this type can be created from the specified Postgres Type.

fn from_sql_null( ty: &Type ) -> Result<Self, Box<dyn Error + Sync + Send, Global>>

Creates a new value of this type from a NULL SQL value.

fn from_sql_nullable( ty: &Type, raw: Option<&'a [u8]> ) -> Result<Self, Box<dyn Error + Sync + Send, Global>>

A convenience function that delegates to from_sql and from_sql_null depending on the value of raw.

impl<T> PartialEq<Date<T>> for Date<T>where T: PartialEq<T>,

fn eq(&self, other: &Date<T>) -> 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<T> ToSql for Date<T>where T: ToSql,

fn to_sql( &self, ty: &Type, out: &mut BytesMut ) -> Result<IsNull, Box<dyn Error + Sync + Send, Global>>

Converts the value of self into the binary format of the specified Postgres Type, appending it to out.

fn accepts(ty: &Type) -> bool

Determines if a value of this type can be converted to the specified Postgres Type.

fn to_sql_checked( &self, ty: &Type, out: &mut BytesMut ) -> Result<IsNull, Box<dyn Error + Sync + Send, Global>>

An adaptor method used internally by Rust-Postgres.

fn encode_format(&self, _ty: &Type) -> Format

Specify the encode format

impl<T> Copy for Date<T>where T: Copy,

impl<T> Eq for Date<T>where T: Eq,

impl<T> StructuralEq for Date<T>

impl<T> StructuralPartialEq for Date<T>
