Wrapper for IDBVersionChangeEvent

Implementations§

Source§

impl<Err> VersionChangeEvent<Err>

Source

pub fn old_version(&self) -> u32

The version before the database upgrade, clamped to u32::MAX

Internally, this uses IDBVersionChangeEvent::oldVersion

Source

pub fn new_version(&self) -> u32

The version after the database upgrade, clamped to u32::MAX

Internally, this uses IDBVersionChangeEvent::newVersion

Source

pub fn database(&self) -> &Database<Err>

The database under creation

Source

pub fn transaction(&self) -> &Transaction<Err>

The versionchange transaction that triggered this event

This transaction can be used to submit further requests.
