Enum OpenGLContextOwnership 

#[non_exhaustive]
pub enum OpenGLContextOwnership {
    Shared,
    Dedicated,
    Unknown(u32),
}

How a session’s OpenGL context relates to the thread that attached it.

A shared session leaves the thread as it found it: every render makes the session context current and restores whatever was current before. The session context joins the host share group the descriptor names, so a host may hand the session a texture and sample it from its own context.

A dedicated session owns the thread. It makes its context current once and keeps it current between renders, and it joins no share group. Use this when a thread exists to drive one render session and runs no other graphics work.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Shared

The session shares its thread with host graphics work.

Dedicated

The session owns its thread’s OpenGL context.

Unknown(u32)

Implementations

impl OpenGLContextOwnership

pub fn from_raw(raw: u32) -> OpenGLContextOwnership

pub fn as_raw(self) -> u32

Trait Implementations

impl Clone for OpenGLContextOwnership

fn clone(&self) -> OpenGLContextOwnership

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OpenGLContextOwnership

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

Formats the value using the given formatter.

impl Default for OpenGLContextOwnership

fn default() -> OpenGLContextOwnership

Returns the “default value” for a type.

impl Hash for OpenGLContextOwnership

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for OpenGLContextOwnership

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