CoerceToDomain

CoerceToDomain represents the operation of coercing a value to a domain type. At runtime (and not before) the precise set of constraints to be checked will be determined. If the value passes, it is returned as the result; if not, an error is raised. Note that this is equivalent to RelabelType in the scenario where no constraints are applied.

Fields

xpr: Expr

arg: *mut Expr

resulttype: Oid

input expression

resulttypmod: int32

domain type ID (result type)

resultcollid: Oid

output typmod (currently always 1)

coercionformat: CoercionForm

OID of collation, or InvalidOid if none

location: c_int
