}

An error produced when using CustomCursor::from_rgba with invalid arguments.

Variants

TooLarge

Produced when the image dimensions are larger than MAX_CURSOR_SIZE. This doesn’t guarantee that the cursor will work, but should avoid many platform and device specific limits.

Fields

width: u16

height: u16

ByteCountNotDivisibleBy4

Produced when the length of the rgba argument isn’t divisible by 4, thus rgba can’t be safely interpreted as 32bpp RGBA pixels.

Fields

byte_count: usize

DimensionsVsPixelCount

Produced when the number of pixels (rgba.len() / 4) isn’t equal to width * height. At least one of your arguments is incorrect.

Fields

width: u16

height: u16

width_x_height: u64

pixel_count: u64

HotspotOutOfBounds

Produced when the hotspot is outside the image bounds

Fields

width: u16

height: u16

hotspot_x: u16

hotspot_y: u16

Trait Implementations

impl Clone for BadImage

fn clone(&self) -> BadImage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BadImage

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

Formats the value using the given formatter.

impl Display for BadImage

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

Formats the value using the given formatter.

impl Error for BadImage

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 Hash for BadImage

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 BadImage

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