Rusqlite is an embedded database interface and relational database driver that provides a client library for interacting with SQLite. It functions as an SQL query wrapper, enabling the management of local file-based or in-memory databases through a safe interface.
The library allows for the extension of native database capabilities by implementing custom scalar functions, collations, and virtual tables. It also supports the embedding of the database engine directly into the application binary to remove external library dependencies.
The project covers a broad range of capabilities including atomic transaction management, prepared statement caching, and the mapping of database values to native application types. It provides utilities for online backups, database serialization, and the streaming of binary large objects.
Operational control is provided through schema inspection, resource limit management, and activity monitoring via event hooks and error logging.
