Provides the serialisation mechanism of a value to a CQL string.
Provides the serialisation mechanism of a value to a CQL string. The vast majority of serializers are fed in via the Primitives mechanism.
Primitive columns will automatically override and define "asCql" based on the serialization of specific primitives. When T is context bounded by a primitive:
def asCql(v: T): String = implicitly[Primitive[T]].asCql(value)
The value of the object to convert to a string.
A string that can be directly appended to a CQL query.
Whether or not this is a compound primitive type that should free if the type of primitive is a collection.
Whether or not this is a compound primitive type that should free if the type of primitive is a collection.
This means that Cassandra will serialise your collection to a blob instead of a normal index based collection storage, so things like index access will not be available.
One such scenario is using a list as part of the primary key, because of how Cassandra works, we need to treat the list as a blob, as if we change its contents we would breach basic rules of serialisation/hashing.
A boolean that says whether or not this type should be frozen.
