Functions

func Xsqlite3_fsFS

func Xsqlite3_fsFS(tls *libc.TLS, zName uintptr, pAppData uintptr) uintptr

This function returns a pointer to the VFS implemented in this file. To make the VFS available to SQLite:

sqlite3_vfs_register(sqlite3_fsFS(), 0);

Types

type FS

type FS struct {
	// contains filtered or unexported fields
}

FS represents a SQLite read only file system backed by Go's fs.FS.

func New

func New(fs fs.FS) (name string, _ *FS, _ error)

New creates a new sqlite VFS and registers it. If successful, the file system can be used with the URI parameter `?vfs=<returned name>`.

func (*FS) Close

func (f *FS) Close() error

Close unregisters f and releases its resources.

type Fts5ExtensionApi

type Fts5ExtensionApi = Fts5ExtensionApi1 /* sqlite3.h:12266:33 */

type Fts5ExtensionApi1

type Fts5ExtensionApi1 = struct {
	// contains filtered or unexported fields

} /* sqlite3.h:12266:9 */

type Fts5PhraseIter

type Fts5PhraseIter = Fts5PhraseIter1 /* sqlite3.h:12268:31 */

type Fts5PhraseIter1

type Fts5PhraseIter1 = struct {
	// contains filtered or unexported fields

} /* sqlite3.h:12268:9 */

type VFSFile

type VFSFile = VFSFile1 /* vfs.c:156:24 */

When using this VFS, the sqlite3_file* handles that SQLite uses are actually pointers to instances of type VFSFile.

type VFSFile1

type VFSFile1 = struct {
	// contains filtered or unexported fields

} /* vfs.c:156:9 */

When using this VFS, the sqlite3_file* handles that SQLite uses are actually pointers to instances of type VFSFile.
