Enum screen_13::prelude::BadIcon

pub enum BadIcon {

        width: u32,

}

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

Variants

ByteCountNotDivisibleBy4

Fields

byte_count: usize

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

DimensionsVsPixelCount

Fields

width: u32

height: u32

width_x_height: usize

pixel_count: usize

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

OsError(Error)

Produced when underlying OS functionality failed to create the icon

Trait Implementations

impl Debug for BadIcon

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

Formats the value using the given formatter.

impl Display for BadIcon

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

Formats the value using the given formatter.

impl Error for BadIcon

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

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
