Struct calc_graph::Inspect

pub struct Inspect<C, F> { /* private fields */ }

Provides the opportunity to inspect a node’s value without changing it.

Trait Implementations

impl<C: Calc, F: FnMut(&C::Value)> Calc for Inspect<C, F>

type Value = <C as Calc>::Value

The type of values calculated by the node.

fn add_dep(&mut self, seen: &mut BitSet<u32>, dep: NonZeroUsize)

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

fn eval(&mut self, dirty: &mut BitSet<u32>) -> (NonZeroUsize, C::Value)

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.
