Struct qt_gui::q_image_reader::ImageReaderError

pub struct ImageReaderError(/* private fields */);

This enum describes the different types of errors that can occur when reading images with QImageReader.

C++ enum: QImageReader::ImageReaderError.

C++ documentation:

This enum describes the different types of errors that can occur when reading images with QImageReader.

Implementations

impl ImageReaderError

pub fn to_int(&self) -> c_int

impl ImageReaderError

pub const UnknownError: ImageReaderError = _

An unknown error occurred. If you get this value after calling read(), it is most likely caused by a bug in QImageReader. (C++ enum variant: UnknownError = 0)

pub const FileNotFoundError: ImageReaderError = _

QImageReader was used with a file name, but not file was found with that name. This can also happen if the file name contained no extension, and the file with the correct extension is not supported by Qt. (C++ enum variant: FileNotFoundError = 1)

pub const DeviceError: ImageReaderError = _

QImageReader encountered a device error when reading the image. You can consult your particular device for more details on what went wrong. (C++ enum variant: DeviceError = 2)

pub const UnsupportedFormatError: ImageReaderError = _

Qt does not support the requested image format. (C++ enum variant: UnsupportedFormatError = 3)

pub const InvalidDataError: ImageReaderError = _

The image data was invalid, and QImageReader was unable to read an image from it. The can happen if the image file is damaged. (C++ enum variant: InvalidDataError = 4)

Trait Implementations

impl Clone for ImageReaderError

fn clone(&self) -> ImageReaderError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ImageReaderError

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

Formats the value using the given formatter.

impl From<ImageReaderError> for c_int

fn from(value: ImageReaderError) -> Self

Converts to this type from the input type.

impl From<i32> for ImageReaderError

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for ImageReaderError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
