Enum GLUniformType

#[non_exhaustive]
pub enum GLUniformType {
    None,
    Float,
    Int,
    Uint,
    Bool,
    Vec2,
    Vec3,
    Vec4,
}

This defines the types of the uniforms that GskGLShaders declare.

It defines both what the type is called in the GLSL shader code, and what the corresponding C type is on the Gtk side.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

None

No type, used for uninitialized or unspecified values.

Float

A float uniform

Int

A GLSL int / gint32 uniform

Uint

A GLSL uint / guint32 uniform

Bool

A GLSL bool / gboolean uniform

Vec2

A GLSL vec2 / graphene_vec2_t uniform

Vec3

A GLSL vec3 / graphene_vec3_t uniform

Vec4

A GLSL vec4 / graphene_vec4_t uniform

Trait Implementations

Performs copy-assignment from source.

impl Debug for GLUniformType

Formats the value using the given formatter.

impl From<GLUniformType> for Value

fn from(v: GLUniformType) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for GLUniformType

type Checker = GenericValueTypeChecker<GLUniformType>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl HasParamSpec for GLUniformType

type ParamSpec = ParamSpecEnum

type SetValue = GLUniformType

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str, _: GLUniformType) -> ParamSpecEnumBuilder<'_, GLUniformType>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for GLUniformType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for GLUniformType

fn cmp(&self, other: &GLUniformType) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

impl PartialEq for GLUniformType

fn eq(&self, other: &GLUniformType) -> 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.

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for GLUniformType

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifier of self.

impl ValueType for GLUniformType

type Type = GLUniformType

Type to get the Type from.

impl Copy for GLUniformType
