Enum c3p0_pool_pg::r2d2::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> Debug for Date<T> where
    T: Debug, 

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

Formats the value using the given formatter.

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

fn to_sql(
    &self,
    ty: &Type,
    out: &mut Vec<u8>
) -> Result<IsNull, Box<dyn Error + 'static + 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 Vec<u8>
) -> Result<IsNull, Box<dyn Error + 'static + Sync + Send>>

An adaptor method used internally by Rust-Postgres.

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> FromSql for Date<T> where
    T: FromSql, 

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

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

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

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

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

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: &Date<T>) -> bool

This method tests for !=.
