Struct calc_graph::Source

pub struct Source<T> { /* fields omitted */ }

Holds a value that can be updated directly from outside the graph.

Trait Implementations

impl<T: Clone> Clone for Source<T>

fn clone(&self) -> Source<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Clone> Calc for Source<T>

type Value = T

The type of values calculated by the node.

fn add_dep(&mut self, _seen: &mut BitSet, dep: usize)

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) -> (usize, 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.
