Struct agde::event::Rewinder

pub struct Rewinder<'a> { /* private fields */ }

Struct to apply all the diffs from a specified timestamp to a resource.

See Manager::rewind_from_last_commit for more info.

Implementations

impl<'a> Rewinder<'a>

pub fn rewind_with_modify_diff( &mut self, resource: &str, data: impl Into<Vec<u8>>, diff_modification: impl FnMut(&Difference) -> Cow<'_, Difference> ) -> Result<Vec<u8>, RewindError>

Rewinds the resource back up to the most recent version. diff_modification can be used to change the diff just before it’s applied.

Errors

Passes errors from Difference::apply.

pub fn rewind( &mut self, resource: &str, data: impl Into<Vec<u8>> ) -> Result<Vec<u8>, RewindError>

Rewinds the resource back up to the most recent version.

Errors

Passes errors from Difference::apply.

pub fn events(&self) -> impl Iterator<Item = &Event> + DoubleEndedIterator + '_

Get an iterator over the events stored in this rewinder. The first item is the oldest one. The last is the most recent.

pub fn last_change_to_resource(&self, resource: &str) -> SystemTime

See Manager::last_change_to_resource.
