Enum GlslConstant 

pub enum GlslConstant {
    Float(f64),
    Int(i64),
    Bool(bool),
    Vec(Vec<f64>),
}

Variants

Float(f64)

Int(i64)

Bool(bool)

Vec(Vec<f64>)

Implementations

impl GlslConstant

pub fn to_glsl_literal(&self) -> String

Emit as a GLSL literal string.

pub fn is_zero(&self) -> bool

Is this the additive identity?

pub fn is_one(&self) -> bool

Is this the multiplicative identity?

pub fn add(&self, other: &GlslConstant) -> Option<GlslConstant>

Add two compatible constants.

Trait Implementations

impl Clone for GlslConstant

fn clone(&self) -> GlslConstant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GlslConstant

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

Formats the value using the given formatter.

impl PartialEq for GlslConstant

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
