Enum GLSLVersion 

pub enum GLSLVersion {
    V120,
    V330,
    V450,
    V460,
}

Supported GLSL version targets.

Variants

V120

GLSL 1.20 — OpenGL 2.1 (legacy)

V330

GLSL 3.30 — OpenGL 3.3 (core profile, widespread)

V450

GLSL 4.50 — OpenGL 4.5 (DSA, direct state access era)

V460

GLSL 4.60 — OpenGL 4.6 / SPIR-V interop

Implementations

impl GLSLVersion

pub fn number(self) -> u32

Return the integer version number used in #version directives.

pub fn profile(self) -> &'static str

Return the profile string appended after the version number.

GLSL 1.20 predates the core/compatibility split; later versions default to core.

pub fn version_line(self) -> String

Emit the full #version line.

pub fn supports_layout_location(self) -> bool

Whether this version supports explicit layout(location = …) qualifiers.

pub fn supports_compute(self) -> bool

Whether this version supports compute shaders.

pub fn supports_uint(self) -> bool

Whether this version supports uint / uvec* types.

Trait Implementations

impl Clone for GLSLVersion

fn clone(&self) -> GLSLVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GLSLVersion

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

Formats the value using the given formatter.

impl Display for GLSLVersion

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

Formats the value using the given formatter.

impl Hash for GLSLVersion

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 PartialEq for GLSLVersion

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