Expand description
A action which specifies that some new Entry content is intended to be an update to some old Entry.
This action semantically updates an entry to a new entry. It has the following effects:
- Create a new Entry
- This is the action of that new entry
- Create a metadata relationship between the original entry and this new action
The original action is required to prevent update loops: If you update A to B and B back to A, and then you don’t know which one came first, or how to break the loop.

type Weighed = Update<EntryRateWeight>

§fn weighed(self, weight: EntryRateWeight) -> Update<EntryRateWeight>
fn weighed(self, weight: EntryRateWeight) -> Update<EntryRateWeight>
Add a weight to this unweighed action, making it “weighed”.
The weight is determined by the
weigh
callback, which is run on the
unweighed version of this action.§fn weightless(self) -> Self::Weighed
fn weightless(self) -> Self::Weighed
Add zero weight to this unweighed action, making it “weighed”.
§impl ActionWeighed for Update<EntryRateWeight>
impl ActionWeighed for Update<EntryRateWeight>
type Unweighed = Update<()>
type Weight = EntryRateWeight
§fn into_action(self) -> Action
fn into_action(self) -> Action
Construct the full Action enum with this variant.
§fn unweighed(self) -> Update<()>
fn unweighed(self) -> Update<()>
Erase the rate limiting weight info, creating an “unweighed” version
of this action. This is used primarily by validators who need to run the
weigh
callback on an action they received, and want to make sure their
callback is not using the predefined weight to influence the result.§impl<'arbitrary, W> Arbitrary<'arbitrary> for Update<W>where
