Struct gfx_device_gl::Version

pub struct Version {
    pub is_embedded: bool,
    pub major: u32,
    pub minor: u32,
    pub revision: Option<u32>,
    pub vendor_info: &'static str,
}

A version number for a specific component of an OpenGL implementation

Fields

is_embedded: bool

major: u32

minor: u32

revision: Option<u32>

vendor_info: &'static str

Implementations

impl Version

pub fn new(
    major: u32,
    minor: u32,
    revision: Option<u32>,
    vendor_info: &'static str
) -> Self

Create a new OpenGL version number

pub fn new_embedded(major: u32, minor: u32, vendor_info: &'static str) -> Version

Create a new OpenGL ES version number

pub fn parse(src: &'static str) -> Result<Version, &'static str>

According to the OpenGL specification, the version information is expected to follow the following syntax:

<major>       ::= <number>
<minor>       ::= <number>
<revision>    ::= <number>
<vendor-info> ::= <string>
<release>     ::= <major> "." <minor> ["." <release>]
<version>     ::= <release> [" " <vendor-info>]

Note that this function is intentionally lenient in regards to parsing, and will try to recover at least the first two version numbers without resulting in an Err.

Trait Implementations

impl Clone for Version

fn clone(&self) -> Version

Returns a copy 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

Formats the value using the given formatter.

impl PartialEq<Version> for Version

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