Implementations§

source§

impl Version

source

pub(crate) fn new( major: u32, minor: u32, revision: Option<u32>, vendor_info: String ) -> Self

Create a new OpenGL version number

source

pub(crate) fn new_embedded(major: u32, minor: u32, vendor_info: String) -> Self

Create a new OpenGL ES version number

source

pub(crate) fn parse(src: &str) -> Result<Version, &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.

Notes

WebGL 2 version returned as OpenGL ES 3.0
