Enum iced::window::icon::Error

pub enum Error {
    InvalidData {
        byte_count: usize,
    },
    DimensionsMismatch {
        width: u32,
        height: u32,
        pixel_count: usize,
    },
    OsError(Error),
}

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

Variants

InvalidData

The provided RGBA data isn't divisble by 4.

Therefore, it cannot be safely interpreted as 32bpp RGBA pixels.

Fields of InvalidData

byte_count: usize

The length of the provided RGBA data.

DimensionsMismatch

The number of RGBA pixels does not match the provided dimensions.

Fields of DimensionsMismatch

width: u32

The provided width.

height: u32

The provided height.

pixel_count: usize

The amount of pixels of the provided RGBA data.

OsError(Error)

The underlying OS failed to create the icon.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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(error: BadIcon) -> Self

Performs the conversion.
