DatabaseTransaction

Defines a database transaction, whether it is an open transaction and the type of backend to use

OpenTransaction

Represents an already opened transaction. This is a thin wrapper over DatabaseTransaction. The wrapping behavior is needed to allow transaction agnostic functionalities of the DB traits.

Enums

DatabaseConnection

Handle a database connection depending on the backend enabled by the feature flags. This creates a database pool. This will be Clone unless the feature flag mock is enabled.

TargetDb

When Sqlite is used as a backend, model needs to be split into 4 different databases to avoid locking the database. On Postgres backend, these should actually point to the same database.

Constants

SINGULAR_TABLE_FIXED_ID

Primary key used in tables that contain only a single row.

Traits

HoprDbGeneralModelOperations

Type Aliases

DbTimestamp

Shorthand for the chrono based timestamp type used in the database.

OptTx

Shorthand for optional transaction. Useful for transaction nesting (see HoprDbGeneralModelOperations::nest_transaction).
