Functions ¶
func UnwrapFile ¶
UnwrapFile unwraps a vfs.File, possibly implementing vfs.FileUnwrap, to a concrete type.
func WrapBeginAtomicWrite ¶
WrapBeginAtomicWrite helps wrap vfs.FileBatchAtomicWrite.
func WrapBusyHandler ¶ added in v0.22.0
WrapBusyHandler helps wrap vfs.FilePragma.
func WrapCheckpointDone ¶
WrapCheckpointDone helps wrap vfs.FileCheckpoint.
func WrapCheckpointStart ¶
WrapCheckpointStart helps wrap vfs.FileCheckpoint.

WrapChunkSize helps wrap vfs.FileChunkSize.
func WrapCommitAtomicWrite ¶
WrapCommitAtomicWrite helps wrap vfs.FileBatchAtomicWrite.
func WrapCommitPhaseTwo ¶
WrapCommitPhaseTwo helps wrap vfs.FileCommitPhaseTwo.
func WrapHasMoved ¶
WrapHasMoved helps wrap vfs.FileHasMoved.
func WrapLockState ¶
WrapLockState helps wrap vfs.FileLockState.
func WrapOpen ¶ added in v0.28.0
func WrapOpen(f vfs.VFS, name string, flags vfs.OpenFlag) (file vfs.File, _ vfs.OpenFlag, err error)
WrapOpen helps wrap vfs.VFS.
func WrapOpenFilename ¶
func WrapOpenFilename(f vfs.VFS, name *vfs.Filename, flags vfs.OpenFlag) (file vfs.File, _ vfs.OpenFlag, err error)
WrapOpenFilename helps wrap vfs.VFSFilename.

WrapOverwrite helps wrap vfs.FileOverwrite.
func WrapPersistWAL ¶ added in v0.22.0
WrapPersistWAL helps wrap vfs.FilePersistWAL.
func WrapPowersafeOverwrite ¶
WrapPowersafeOverwrite helps wrap vfs.FilePowersafeOverwrite.
func WrapPragma ¶
WrapPragma helps wrap vfs.FilePragma.
func WrapRollbackAtomicWrite ¶
WrapRollbackAtomicWrite helps wrap vfs.FileBatchAtomicWrite.
func WrapSetPersistWAL ¶ added in v0.22.0
WrapSetPersistWAL helps wrap vfs.FilePersistWAL.
func WrapSetPowersafeOverwrite ¶
WrapSetPowersafeOverwrite helps wrap vfs.FilePowersafeOverwrite.
func WrapSharedMemory ¶
func WrapSharedMemory(f vfs.File) vfs.SharedMemory
WrapSharedMemory helps wrap vfs.FileSharedMemory.
func WrapSizeHint ¶
WrapSizeHint helps wrap vfs.FileSizeHint.
func WrapSyncSuper ¶ added in v0.22.0

Types ¶
type SliceFile ¶ added in v0.28.0
type SliceFile []byte
SliceFile implements vfs.File with a byte slice. It is suitable for temporary files (such as vfs.OPEN_TEMP_JOURNAL), but not concurrency safe.
func (*SliceFile) CheckReservedLock ¶ added in v0.28.0
CheckReservedLock implements vfs.File.
func (*SliceFile) DeviceCharacteristics ¶ added in v0.28.0
func (*SliceFile) DeviceCharacteristics() vfs.DeviceCharacteristic
DeviceCharacteristics implements vfs.File.
func (*SliceFile) ReadAt ¶ added in v0.28.0
ReadAt implements io.ReaderAt.
func (*SliceFile) SectorSize ¶ added in v0.28.0
SectorSize implements vfs.File.
func (*SliceFile) SizeHint ¶ added in v0.28.0
SizeHint implements vfs.FileSizeHint.
