Struct gfx_backend_gl::Version

pub struct Version {
    pub is_embedded: bool,
    pub major: u32,
    pub minor: u32,
    pub revision: Option<u32>,
    pub vendor_info: String,
}

A version number for a specific component of an OpenGL implementation

Fields

is_embedded: bool

major: u32

minor: u32

revision: Option<u32>

vendor_info: String

Methods

impl Version

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

Create a new OpenGL version number

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

Create a new OpenGL ES version number

pub fn tuple(&self) -> (u32, u32)

Get a tuple of (major, minor) versions

pub fn parse(src: String) -> Result<Version, String>

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 Eq for Version

impl Ord for Version

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

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

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: &Version) -> bool

This method tests for !=.

impl PartialOrd<Version> 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: &Version) -> bool

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

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

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

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

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

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

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