T: ValueTree,
T::Value: Clone, [src]
impl<T: Clone> Clone for OptionValueTree<T> where
T: ValueTree,
T::Value: Clone, fn clone(&self) -> OptionValueTree<T>[src]
fn clone(&self) -> OptionValueTree<T>Returns a copy of the value. Read more
fn clone_from(&mut self, source: &Self)1.0.0[src]
fn clone_from(&mut self, source: &Self)1.0.0
[src]Performs copy-assignment from source. Read more
impl<T: Debug> Debug for OptionValueTree<T> where
T: ValueTree,
T::Value: Debug, [src]
impl<T: Debug> Debug for OptionValueTree<T> where
T: ValueTree,
T::Value: Debug, fn fmt(&self, f: &mut Formatter) -> Result[src]
fn fmt(&self, f: &mut Formatter) -> ResultFormats the value using the given formatter. Read more
impl<T> ValueTree for OptionValueTree<T> where
T: ValueTree, [src]
impl<T> ValueTree for OptionValueTree<T> where
T: ValueTree, type Value = Option<T::Value>
The type of the value produced by this ValueTree.
fn current(&self) -> Self::Value[src]
fn current(&self) -> Self::ValueReturns the current value.
fn simplify(&mut self) -> bool[src]
fn simplify(&mut self) -> boolAttempts 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. Read more
fn complicate(&mut self) -> bool[src]
fn complicate(&mut self) -> boolAttempts 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. Read more
