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"]

Trait Implementations

impl QueryId for Numeric

type QueryId = Numeric
