struct Cassandra::DBApi::Any

Cassandra::DBApi::Any
Struct
Value
Object

Overview

Wraps any possible Cassandra value. It can be supplied as a parameter for a query or be returned as a result. It dynamically handles values with actual types decided at runtime.

Cassandra::DBApi::Any serves a similar purpose as JSON::Any.

In order to obtain the actual value use the as_* methods which perform type checks against the raw underlying value.

Defined in:

cassandra/dbapi.cr

Constructors

.new(raw : Type)
Creates a Cassandra::DBApi::Any that wraps the given value.
