Enum Version 

pub enum Version {
    Desktop(u16),
    Embedded {
        version: u16,
        is_webgl: bool,
    },
}

A GLSL version.

Variants

Desktop(u16)

core GLSL.

Embedded

es GLSL.

Fields

version: u16

is_webgl: bool

Implementations

impl Version

pub const fn new_gles(version: u16) -> Version

Create a new gles version

pub const fn is_es(&self) -> bool

Returns true if self is Version::Embedded (i.e. is a es version)

pub const fn is_webgl(&self) -> bool

Returns true if targeting WebGL

pub fn is_supported(&self) -> bool

Checks the list of currently supported versions and returns true if it contains the specified version

Notes

As an invalid version number will never be added to the supported version list so this also checks for version validity

pub fn supports_io_locations(&self) -> bool

pub fn supports_explicit_locations(&self) -> bool

Checks if the version supports all of the explicit layouts:

• location= qualifiers for bindings
• binding= qualifiers for resources

Note: location= for vertex inputs and fragment outputs is supported unconditionally for GLES 300.

pub fn supports_early_depth_test(&self) -> bool

pub fn supports_std140_layout(&self) -> bool

pub fn supports_std430_layout(&self) -> bool

pub fn supports_fma_function(&self) -> bool

pub fn supports_integer_functions(&self) -> bool

pub fn supports_frexp_function(&self) -> bool

pub fn supports_derivative_control(&self) -> bool

pub fn supports_pack_unpack_4x8(&self) -> bool

pub fn supports_pack_unpack_snorm_2x16(&self) -> bool

pub fn supports_pack_unpack_unorm_2x16(&self) -> bool

pub fn supports_pack_unpack_half_2x16(&self) -> bool

Trait Implementations

impl Clone for Version

fn clone(&self) -> Version

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Version

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Version

fn deserialize<__D>( __deserializer: __D, ) -> Result<Version, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Version

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

Formats the value using the given formatter.

impl PartialEq for Version

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

impl PartialOrd for Version

fn partial_cmp(&self, other: &Version) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

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

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

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.

impl Serialize for Version

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Version

impl StructuralPartialEq for Version
