Perform the conversion

impl AsExpression<Nullable<Numeric>> for PgNumeric

type Expression = Bound<Nullable<Numeric>, PgNumeric>

The expression being returned

fn as_expression(self) -> Self::Expression

Perform the conversion

impl<'expr> AsExpression<Numeric> for &'expr PgNumeric

Performs copy-assignment from source.

impl Debug for PgNumeric

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

Formats the value using the given formatter.

impl<'a> From<&'a BigDecimal> for PgNumeric

Available on crate feature bigdecimal only.

fn from(decimal: &'a BigDecimal) -> Self

Converts to this type from the input type.

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

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