Struct Value 

pub struct Value {
    pub argument: Argument,
    pub curve: Curve,
    pub variation: Vec<Variation>,
}

A scalar or vector quantity that may vary with time and at random: what every parameter of an emitter is.

Fields

argument: Argument

What the curve is a function of.

curve: Curve

The base value.

variation: Vec<Variation>

Variations applied to it, in order.

Implementations

impl Value

pub fn constant(values: &[f32]) -> Value

A constant that does not vary.

pub fn is_fixed(&self) -> bool

Whether the value is a constant that does not vary.

impl Value

pub fn eval( &self, x: f32, seed: u64, emitter: u32, scope: u64, input: &dyn Fn(u32) -> f32, ) -> [f32; 4]

The value at argument x for the draw scope of emitter in a system of seed, with the system’s inputs read through input (by index): the curve, then the variations in order.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Self

Returns a duplicate of the value.

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

impl PartialEq for Value

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for Value

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,
