Module diesel::expression::helper_types [−] [src]

The types in this module are all shorthand for PredicateType<Lhs, AsExpr<Rhs, Lhs>>. Since we often need to return concrete types, instead of a boxed trait object, these can be useful for writing concise return types.

Type Definitions

And	The return type of `lhs.and(rhs)`
AsExpr	The type of `Item` when converted to an expression with the same type as `TargetExpr`
AsExprOf	The type of `Item` when converted to an expression of `Type`
Between	The return type of `lhs.between(lower, upper)`
Eq	The return type of `lhs.eq(rhs)`
EqAny	The return type of `lhs.eq_any(rhs)`
Gt	The return type of `lhs.gt(rhs)`
GtEq	The return type of `lhs.ge(rhs)`
Like	The return type of `lhs.like(rhs)`
Lt	The return type of `lhs.lt(rhs)`
LtEq	The return type of `lhs.le(rhs)`
Not	The return type of `not(expr)`
NotBetween	The return type of `lhs.not_between(lower, upper)`
NotEq	The return type of `lhs.ne(rhs)`
NotLike	The return type of `lhs.not_like(rhs)`
SqlTypeOf	The SQL type of an expression
