Enum PixelsError 

pub enum PixelsError {
    Unavailable,
    TooLarge {
        width: u32,
        height: u32,
        max: u32,
    },
    Failed(String),
}

Why a scene’s pixels did not come.

Variants

Unavailable

This host renders no pixels for apps: it has no GPU, or its thread cannot wait and no frame loop renders them.

TooLarge

The GPU cannot hold a picture this size; max is its longest side.

Fields

width: u32

height: u32

max: u32

Failed(String)

Rendering them, or reading them back, failed.

Trait Implementations

impl Clone for PixelsError

fn clone(&self) -> PixelsError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PixelsError

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

Formats the value using the given formatter.

impl Display for PixelsError

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

Formats the value using the given formatter.

impl Error for PixelsError

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 PixelsError

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