Struct Values 

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

Read-only value-level view over a node fn’s dependency snapshot (D27/R-primary-api-clean).

Values exposes DATA-oriented dep state (latest, prev, batch, terminal state) without the ctx-level power surface (up, down, rewire_next). Graph derived and effect use this canonical Rust value API; node/producer remain the ctx-level escape hatch.

Implementations

impl<'a> Values<'a>

pub fn len(&self) -> usize

Updates or reads len.

pub fn is_empty(&self) -> bool

Updates or reads is_empty.

pub fn prev<T: 'static>(&self, i: usize) -> Option<Rc<T>>

Value-level derived helper: last committed DATA before dep i’s current batch. This is graph sugar, not part of the raw Ctx dep-value surface (D77).

pub fn batches<T: 'static>(&self, i: usize) -> Vec<Vec<Rc<T>>>

DATA payloads dep i delivered before this run, grouped by upstream wave.

pub fn terminal(&self, i: usize) -> Option<&DepTerminal>

Terminal state for dep i, when terminal-as-real-input sugar needs it.
