Struct DataChecklist 

pub struct DataChecklist<'a, T> { /* private fields */ }

A Checklist of documents that must be verified before the contained data is yielded.

A checklist can be completed by performing the following steps:

1. Call iter to get an iterator over the list.
2. For each item, fetch the Document matching the hash that was provided alongside the item, then provide it to the item by calling check.
3. When all the items have been completed successfully, call complete to get the contained data.

Implementations

impl<'a, T> DataChecklist<'a, T>

pub fn iter(&mut self) -> impl Iterator<Item = (Hash, ListItem<'_>)>

Iterate through the whole checklist, going through one Hash and list item at a time. For each item, look up a Document with the same hash and check it with the ListItem’s check function.

pub fn complete(self) -> Result<T>

Complete a checklist, yielding the inner data value if the checklist was successfully iterated over.
