Overview ¶
Package volume_idb implements the browser volume engines' storage primitives on IndexedDB: a chunked device.Device and a records.Store.
Every call is one IndexedDB transaction. A call issues all of its requests in one JavaScript task and returns on the transaction's complete event, so the Go code blocks only once per call.

Constants ¶
const ChunkSize = 64 << 10
ChunkSize is the length of a full chunk.

Functions ¶
func DeleteDatabase ¶
DeleteDatabase deletes the database name. A missing database is not an error.
Types ¶
type Device ¶
type Device struct {
// contains filtered or unexported fields
}
Device is a device.Device on one IndexedDB database. It is the database's only writer, enforced by an exclusive Web Lock held from OpenDevice until Close: it holds the file lengths and the last chunk written to each file, so appends need no read.
func OpenDevice ¶
OpenDevice opens the device database name, creating it when absent. It returns device.ErrHeld while another Device in the origin has name open.
type Store ¶
type Store struct {
// contains filtered or unexported fields
}
Store is a records.Store on one IndexedDB database.
