pub struct Update1<C1, T, F> { /* fields omitted */ }

Calculates a value from the value currently in this node and another node.

Trait Implementations

impl<C1: Calc, T: Clone, F: FnMut(&mut T, C1::Value) -> bool> Calc for Update1<C1, T, F>

type Value = T

The type of values calculated by the node.

fn eval(&mut self, dirty: &mut BitSet) -> (NonZeroUsize, T)

Returns the value held within the node and the version number of the inputs used to calcuate that value. The value is recalculated if needed.

fn add_dep(&mut self, seen: &mut BitSet, dep: NonZeroUsize)

When this node is used as a precedent, add_dep is called by dependent nodes when they are created.
