Constraint types between parameters.

Variants

MinRelative

target must be >= source * factor + offset

Fields

source: String

target: String

factor: f32

offset: f32

MaxRelative

target must be <= source * factor + offset

Fields

source: String

target: String

factor: f32

offset: f32

Driven

target = source * factor + offset (hard link), clamped to [0, 1]

Fields

source: String

target: String

factor: f32

offset: f32

SumEquals

sum of named params must equal total (redistributes proportionally)

Fields

params: Vec<String>

total: f32

Clamp

param must be in [min, max]

Fields

param: String

min: f32

max: f32

MaxSum

param_a + param_b <= max_sum

Fields

param_a: String

param_b: String

max_sum: f32

Conditional

if condition_param >= threshold, then target_param gets assigned value

Fields

condition: String

threshold: f32

target: String

value: f32

Implementations

impl Constraint

pub fn apply(&self, params: &mut Params) -> bool

Apply this constraint to params in-place, return true if any change was made.

pub fn is_satisfied(&self, params: &Params) -> bool

Check if the constraint is currently satisfied.

pub fn describe(&self) -> String

Name/description of constraint for debugging.

Trait Implementations

impl Clone for Constraint

fn clone(&self) -> Constraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Constraint

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

Formats the value using the given formatter.
