Enum egui_glow::shader_version::ShaderVersion

pub enum ShaderVersion {
    Gl120,

    Es100,
    Es300,
}

Helper for parsing and interpreting the OpenGL shader version.

Variants

Gl120

Gl140

OpenGL 1.4 or later

e.g. WebGL1

Es300

e.g. WebGL2

Implementations

impl ShaderVersion

pub fn get(gl: &Context) -> Self

pub(crate) fn parse(glsl_ver: &str) -> Self

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

Goes on top of the shader.

pub fn is_new_shader_interface(&self) -> bool

If true, use in/out. If false, use varying and gl_FragColor.

pub fn is_embedded(&self) -> bool

Trait Implementations

impl Clone for ShaderVersion

fn clone(&self) -> ShaderVersion

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ShaderVersion

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

Formats the value using the given formatter.

impl PartialEq<ShaderVersion> for ShaderVersion

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

This method tests for self and other values to be equal, and is used by ==.

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

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