Enum wry::application::window::BadIcon

#[non_exhaustive]
pub enum BadIcon {
    ByteCountNotDivisibleBy4 {
        byte_count: usize,
    },
    DimensionsVsPixelCount {
        width: u32,

        width_x_height: usize,

    OsError(Error),
}

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

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ByteCountNotDivisibleBy4

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

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

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

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

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

Formats the value using the given formatter.

impl Display for BadIcon

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

Formats the value using the given formatter.

impl Error for BadIcon

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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

impl From<BadIcon> for Error

fn from(source: BadIcon) -> Self

Performs the conversion.
