Enum Error 

#[non_exhaustive]
pub enum Error {
    Xcb(Error),
    BadScreenNumber(i32),
    UnsupportedVisual(u8, VisualClass),
    CouldNotFindRootVisual(Visualid),
    ImageTooLarge(u32, u32),
    BadBufferSize(usize, u16, u16),
    Image(ImageError),
}

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.

Xcb(Error)

XCB error as a result of an X request.

BadScreenNumber(i32)

Unrecognised screen number, i.e. negative or does not match any existing screen.

UnsupportedVisual(u8, VisualClass)

Display server uses unsupported visual. This library supports 24- or 32-bit TrueColour visual only.

CouldNotFindRootVisual(Visualid)

Failed to locate visual that matches the root visual.

ImageTooLarge(u32, u32)

Image too large. Image dimensions must fit 16-bit unsigned integer.

BadBufferSize(usize, u16, u16)

The image buffer size does not match image dimensions.

Image(ImageError)

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, __derive_more_f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

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
