Struct diesel::sql_types::Numeric

pub struct Numeric;

The arbitrary precision numeric SQL type.

This type is only supported on PostgreSQL and MySQL. On SQLite, Double should be used instead.

ToSql impls

• bigdecimal::BigDecimal with feature = ["numeric"]

FromSql impls

• bigdecimal::BigDecimal with feature = ["numeric"]

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>
