Trait Implementations

impl<T: Clone> Clone for TupleUnionValueTree<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Copy> Copy for TupleUnionValueTree<T>

impl<T: Debug> Debug for TupleUnionValueTree<T>

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<A: ValueTree, B: ValueTree<Value = A::Value>> ValueTree for TupleUnionValueTree<(A, Option<B>)>

type Value = A::Value

The type of the value produced by this ValueTree.

fn current(&self) -> Self::Value

Returns the current value.

fn simplify(&mut self) -> bool

Attempts to simplify the current value. Notionally, this sets the "high" value to the current value, and the current value to a "halfway point" between high and low, rounding towards low.

fn complicate(&mut self) -> bool

Attempts to partially undo the last simplification. Notionally, this sets the "low" value to one plus the current value, and the current value to a "halfway point" between high and the new low, rounding towards low.
