In practice, this is an alias for Foreign with type system guarantees that purescript types are correctly represented in JS to be represented in SQL.

Instances

Show Raw
(Warn (Text "`Eq Raw` only checks equality for JS primitives, and is always `false` for objects.")) => Eq Raw

#rawToDebugString Source

rawToDebugString :: Raw -> String

Stringifies a Raw value if a JS primitive, else returns a debug representation.

{foo: 'bar'} -> "[Object]"
[1, 2, 3] -> "[Array]"
'foo' -> "foo"
123 -> "123"

#rawDebugEq Source

rawDebugEq :: Raw -> Raw -> Boolean

Performs JS referential equality === for primitives or arrays of primitives, else returns false.

#rawMaybeNull Source

rawMaybeNull :: Maybe Raw -> Raw

#rawNullMaybe Source

rawNullMaybe :: Raw -> Maybe Raw

#unsafeFromForeign Source

unsafeFromForeign :: Foreign -> Raw

Coerce a Foreign value to Raw.

This is only safe if the Foreign value is guaranteed to be serializable to a SQL value via pg-types.

#asForeign Source
