Enum 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)

Trait Implementations

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

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

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>>

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>>

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

impl<T: ToSql> ToSql for Date<T>

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

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>>

An adaptor method used internally by Rust-Postgres.

impl<T: Clone> Clone for Date<T>

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: Copy> Copy for Date<T>

impl<T: PartialEq> PartialEq<Date<T>> for Date<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: &Date<T>) -> bool

This method tests for !=.

impl<T: Debug> Debug for Date<T>

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

Formats the value using the given formatter.
