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

Methods

impl Version

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

Create a new OpenGL version number

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

Create a new OpenGL ES version number

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 PartialOrd for Version

fn partial_cmp(&self, __arg_0: &Version) -> Option<Ordering>

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

fn lt(&self, __arg_0: &Version) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, __arg_0: &Version) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, __arg_0: &Version) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, __arg_0: &Version) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl PartialEq for Version

fn eq(&self, __arg_0: &Version) -> bool

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

fn ne(&self, __arg_0: &Version) -> bool

This method tests for !=.

impl Ord for Version

fn cmp(&self, __arg_0: &Version) -> Ordering

This method returns an Ordering between self and other.

impl Eq for Version

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 Copy for Version

impl Debug for Version

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

Formats the value using the given formatter.
