Typedef Documentation

backend_factory_fn

using database::core::backend_factory_fn = std::unique_ptr<database_backend> (*)()

Factory function type for creating database backends.

This function signature is used by backend_registry to instantiate backends. Each backend implementation should provide a create() function matching this signature.

Returns

Unique pointer to newly created backend instance

Definition at line 307 of file database_backend.h.

database_result

using database::core::database_result = std::vector<database_row>

Examples

/home/runner/work/database_system/database_system/database/async/async_operations.h, and /home/runner/work/database_system/database_system/database/orm/entity.h.

Definition at line 41 of file database_backend.h.

database_row

using database::core::database_row = std::map<std::string, database_value>

Definition at line 40 of file database_backend.h.

database_value

using database::core::database_value = std::variant<std::string, int64_t, double, bool, std::nullptr_t>

Examples

/home/runner/work/database_system/database_system/database/orm/entity.h.

Definition at line 39 of file database_backend.h.

create_backend()

std::unique_ptr< database_backend > database::core::create_backend ( const std::string & name )

inline

Convenience function for creating backends (static method style)

Parameters

name	Backend name

Returns

Unique pointer to backend, or nullptr if not found

This is a convenience wrapper around backend_registry::instance().create() for more concise code.

Example:

auto backend = create_backend("postgresql");

has_backend()

bool database::core::has_backend ( const std::string & name )

inline

Parameters

name	Backend name to check

Returns
