Struct UpdatesBuilder 

pub struct UpdatesBuilder<U: Update> { /* private fields */ }

An incremental trie builder that accepts sorted, consolidated UpdatesTyped chunks and melds them into a single UpdatesTyped trie.

The internal UpdatesTyped has open (unsealed) bounds at the keys, vals, and times levels — the last group at each level has its values pushed but no corresponding bounds entry. diffs.bounds is always 1:1 with times.values.

meld accepts a consolidated UpdatesTyped whose first (key, val, time) is strictly greater than the builder’s last (key, val, time). The key and val may equal the builder’s current open key/val, as long as the time is greater.

done seals all open bounds and returns the completed UpdatesTyped.

Implementations

impl<U: Update> UpdatesBuilder<U>

pub fn new_from(updates: UpdatesTyped<U>) -> Self

Construct a new builder from consolidated, sealed updates.

Unseals the last group at keys, vals, and times levels so that subsequent meld calls can extend the open groups. If the updates are not consolidated none of this works.

pub fn meld(&mut self, chunk: &UpdatesTyped<U>)

Meld a sorted, consolidated UpdatesTyped chunk into this builder.

The chunk’s first (key, val, time) must be strictly greater than the builder’s last (key, val, time). Keys and vals may overlap (continue the current group), but times must be strictly increasing within the same (key, val).

pub fn done(self) -> UpdatesTyped<U>

Seal all open bounds and return the completed UpdatesTyped.
