Structs

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

HoprDbAllOperations

Convenience trait that contain all HOPR DB operations crates.

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).
