Expand description

An error produced when using CustomCursorSource::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
