Implementations

impl TrackChangeFetcher

pub fn resume_from(next_url: impl Into<String>) -> Self

Resume a fetching process from url.

The url should be from TrackChangeFetcher::next_url.

pub fn next_url(&self) -> Option<&str>

Try to get the url to the next page.

Used for resuming the fetching progress.

Error

Will success only if there are more pages and the first page is already read.

Note

The first page data from OneDrive::track_changes_from_initial_with_option will be cached and have no idempotent url to resume/re-fetch.

pub fn delta_url(&self) -> Option<&str>

Try to the delta url representing a snapshot of current track change operation.

Used for tracking changes from this snapshot (rather than initial) later, using OneDrive::track_changes_from_delta_url.

Error
