Enum SwapBuffersError

pub enum SwapBuffersError {
    ContextLost,
    AlreadySwapped,
}

Error that can happen when swapping buffers.

Variants

ContextLost

The OpenGL context has been lost and needs to be recreated. The Display and all the objects associated to it (textures, buffers, programs, etc.) need to be recreated from scratch.

Operations will have no effect. Functions that read textures, buffers, etc. from OpenGL will return uninitialized data instead.

A context loss usually happens on mobile devices when the user puts the application on sleep and wakes it up later. However any OpenGL implementation can theoretically lose the context at any time. Can only happen if calling is_context_loss_possible() returns true.

AlreadySwapped

The buffers have already been swapped.

This error can be returned when set_finish() is called multiple times, or finish() is called after set_finish().

Trait Implementations

impl Clone for SwapBuffersError

fn clone(&self) -> SwapBuffersError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SwapBuffersError

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

Formats the value using the given formatter.

impl Display for SwapBuffersError

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

Formats the value using the given formatter.

impl Error for SwapBuffersError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl PartialEq for SwapBuffersError

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