core

Top-level import, providing aliases for the most commonly used types and modules from doobie-free and doobie-core. A typical starting set of imports would be something like this.

import cats.implicits.*
import doobie._, doobie.implicits.*

Enumerated types for JDBC constants. enumerated values are provided by companion modules.

High-level database API. The constructors here are defined in terms of those in doobie.free.connection but differ in the following ways:

• Enumerated values represented by Int values in JDBC are mapped to one of the proper types defined in doobie.enumerated.
• Nullable values are represented in terms of Option.
• Java collection types are translated to immutable Scala equivalents.
• Actions that compute lifetime-managed resources do not return the resource directly, but rather take a continuation in the resource's monad.
• Actions that compute values of impure types (CLOB, InputStream, etc.) do not appear in this API. They are available in the low-level API but must be used with considerable caution.
• Lifting actions, low-level type mapping actions, and resource management actions do not appear in this API.
