Struct qt_gui::q_image_writer::ImageWriterError

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

This enum describes errors that can occur when writing images with QImageWriter.

C++ enum: QImageWriter::ImageWriterError.

C++ documentation:

This enum describes errors that can occur when writing images with QImageWriter.

Implementations

impl ImageWriterError

pub fn to_int(&self) -> c_int

impl ImageWriterError

pub const UnknownError: ImageWriterError = _

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

pub const DeviceError: ImageWriterError = _

QImageWriter encountered a device error when writing the image data. Consult your device for more details on what went wrong. (C++ enum variant: DeviceError = 1)

pub const UnsupportedFormatError: ImageWriterError = _

Qt does not support the requested image format. (C++ enum variant: UnsupportedFormatError = 2)

pub const InvalidImageError: ImageWriterError = _

An attempt was made to write an invalid QImage. An example of an invalid image would be a null QImage. (C++ enum variant: InvalidImageError = 3)

Trait Implementations

impl Clone for ImageWriterError

fn clone(&self) -> ImageWriterError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ImageWriterError

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

Formats the value using the given formatter.

impl From<ImageWriterError> for c_int

fn from(value: ImageWriterError) -> Self

Converts to this type from the input type.

impl From<i32> for ImageWriterError

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for ImageWriterError

fn eq(&self, other: &ImageWriterError) -> 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.
