Enum OverlayImageError 

pub enum OverlayImageError {
    Size {
        width: u32,
        height: u32,
    },
    Length {
        expected: usize,
        got: usize,
    },
}

Why Renderer::set_overlay_image refused an image. Nothing changes on a refusal: an image already set stays set.

Variants

Size

A dimension is zero, or larger than the adapter’s 2D texture limit.

Fields

width: u32

The width asked for.

height: u32

The height asked for.

Length

The byte count is not width * height * 4.

Fields

expected: usize

width * height * 4.

got: usize

The bytes handed over.

Trait Implementations

impl Clone for OverlayImageError

fn clone(&self) -> OverlayImageError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OverlayImageError

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

Formats the value using the given formatter.

impl Display for OverlayImageError

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

Formats the value using the given formatter.

impl Error for OverlayImageError

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 OverlayImageError

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