type Value = Option<T::Value>
The type of the value produced by this ValueTree
.
fn current(&self) -> Self::Value
[src]
fn current(&self) -> Self::Value
Returns the current value.
fn simplify(&mut self) -> bool
[src]
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. Read more
fn complicate(&mut self) -> bool
[src]
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. Read more
