Expand description

Trait for stored vectors that persist data to disk (as opposed to lazy computed vectors).

Required Methods§

Source

fn saved_stamped_changes(&self) -> u16

Number of stamped change files to keep for rollback support.

Source

fn real_stored_len(&self) -> usize

The actual length stored on disk.

Source

fn stored_len(&self) -> usize

The effective stored length (may differ from real_stored_len during truncation).

Source

fn any_stamped_write_with_changes(&mut self, stamp: Stamp) -> Result<()>

Flushes with the given stamp, saving changes to enable rollback. Prefixed with any_ to avoid conflict with WritableVec::stamped_write_with_changes.
