Struct postgres_parser::sys::CoerceToDomainValue

#[repr(C)]pub struct CoerceToDomainValue {
    pub xpr: Expr,
    pub typeId: Oid,
    pub typeMod: int32,
    pub collation: Oid,
    pub location: c_int,
}

Placeholder node for the value to be processed by a domain's check constraint. This is effectively like a Param, but can be implemented more simply since we need only one replacement value at a time.

Note: the typeId/typeMod/collation will be set from the domain's base type, not the domain itself. This is because we shouldn't consider the value to be a member of the domain if we haven't yet checked its constraints.

Fields

xpr: Expr

typeId: Oid

typeMod: int32

type for substituted value

collation: Oid

typemod for substituted value

location: c_int

collation for the substituted value
