Enum BadIcon

pub enum BadIcon {
    ByteCountNotDivisibleBy4 {
        byte_count: usize,
    },
    DimensionsVsPixelCount {
        width: u32,
        height: u32,
        width_x_height: usize,
        pixel_count: usize,
    },
    OsError(Error),
}

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

Variants

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: u32

height: u32

width_x_height: usize

pixel_count: usize

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)>

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.
