Enum ImageError 

#[non_exhaustive]
pub enum ImageError {
    ZeroSize {
        width: u32,
        height: u32,
    },
    PixelCount {
        expected: usize,
        found: usize,
    },
}

Why an Image could not be built.

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.

ZeroSize

The width or the height is zero, so the image has no pixel.

Fields

width: u32

The width asked for, in pixels.

height: u32

The height asked for, in pixels.

PixelCount

The pixel buffer’s length does not match the width, height and format.

Fields

expected: usize

The length the width and height call for, in bytes, or usize::MAX when that length does not fit in a usize.

found: usize

The length the buffer has, in bytes.

Trait Implementations

impl Clone for ImageError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ImageError

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

Formats the value using the given formatter.

impl Display for ImageError

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

Formats the value using the given formatter.

impl Eq for ImageError

impl Error for ImageError

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.

impl PartialEq for ImageError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
