Shrinks an integer towards 0, using binary search to find boundary points.
Methods
impl BinarySearch
[src]
fn new(start: u32) -> Self
[src]

the given lo
value.
Trait Implementations

impl Copy for BinarySearch
[src]
impl Debug for BinarySearch
[src]
impl ValueTree for BinarySearch
[src]
type Value = u32
The type of the value produced by this ValueTree
.
fn current(&self) -> u32
[src]
Returns the current value.
fn simplify(&mut self) -> bool
[src]
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]
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
