impl Clone for PgNumeric

fn clone(&self) -> PgNumeric

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PgNumeric

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

Formats the value using the given formatter.

impl FromSql<Numeric, Pg> for PgNumeric

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 PartialEq for PgNumeric

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

Tests for self and other values to be equal, and is used by ==.

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

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

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

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

type Row = PgNumeric

The Rust type you’d like to map from.

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

Construct an instance of this type

impl<__DB> ToSql<Nullable<Numeric>, __DB> for PgNumeric

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

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