Struct ScalarCache 

Source 
struct ScalarCache<'m> {
    values: &'m mut [f32],
}
Expand description

The scalar for each region at one location, computed on first use.

Fields§

§values: &'m mut [f32]

Implementations§

Source§

impl<'m> ScalarCache<'m>

Source

const INVALID: f32 = 2.0

Marks a scalar that has not been computed.

Scalars are in [0, 1], so this value is never valid.

Source

fn new(values: &'m mut [f32]) -> Self

Source

fn get(&self, index: usize) -> f32

Source

fn set(&mut self, index: usize, value: f32)
