The expression being returned

fn as_expression(self) -> Self::Expression

Perform the conversion

impl AsExpression<Nullable<Quantity>> for Quantity

type Expression = Bound<Nullable<Quantity>, Quantity>

The expression being returned

fn as_expression(self) -> Self::Expression

Perform the conversion

impl<'a> AsExpression<Quantity> for &'a Quantity

impl AsExpression<Quantity> for Quantity

type Expression = Bound<Quantity, Quantity>

The expression being returned

fn as_expression(self) -> Self::Expression

impl Clone for Quantity

fn clone(&self) -> Quantity

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Quantity

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Quantity

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromSql<Quantity, Pg> for Quantity

fn from_sql(raw: PgValue<'_>) -> Result<Self>

See the trait documentation.

fn from_nullable_sql( bytes: Option<<DB as HasRawValue<'_>>::RawValue>, ) -> Result<Self, Box<dyn Error + Send + Sync>>

A specialized variant of from_sql for handling null values.

impl PartialEq for Quantity

fn eq(&self, other: &Quantity) -> 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 Queryable<Quantity, Pg> for Quantity

type Row = Quantity

The Rust type you’d like to map from.

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

Construct an instance of this type

impl Serialize for Quantity

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'__s> ToSchema<'__s> for Quantity

fn schema() -> (&'__s str, RefOr<Schema>)

Return a tuple of name and schema or reference to a schema that can be referenced by the name or inlined directly to responses, request bodies or parameters.

fn aliases() -> Vec<(&'__s str, Schema)>

Optional set of alias schemas for the ToSchema::schema.

impl<DB> ToSql<Nullable<Quantity>, DB> for Quantity

where DB: Backend, Self: ToSql<Quantity, DB>,

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

See the trait documentation.

impl ToSql<Quantity, Pg> for Quantity

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

See the trait documentation.
