pub struct SelectValueTree<T>(_)
 where
    T: Clone + Debug + 'static;

ValueTree corresponding to Select.

Trait Implementations

impl<T: Clone> Clone for SelectValueTree<T> where
    T: Clone + Debug + 'static, 

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for SelectValueTree<T> where
    T: Clone + Debug + 'static, 

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

Formats the value using the given formatter.

impl<T> ValueTree for SelectValueTree<T> where
    T: Clone + Debug + 'static, 

type Value = T

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.
