This repository is a Go library that implements a database/sql driver for SQLite3, using cgo to bind to the SQLite C library (either the bundled amalgamation or a system-installed libsqlite3). It provides a full-featured driver supporting transactions, prepared statements, custom functions, aggregators, collations, hooks, virtual tables, backup, serialization, and many SQLite extensions via build tags. The architecture is a single-package driver with a large cgo file (sqlite3.go) and numerous optional feature files selected by build constraints. Key entry points are the SQLiteDriver, SQLiteConn, SQLiteStmt, and SQLiteRows types, which implement the standard database/sql interfaces. The codebase is mature, widely used, and actively maintained, with extensive tests and CI across platforms. It is not a standalone application but a reusable library consumed by Go programs.
