}

Enum to store the various ways that operations can fail when rendering windows

Variants

InvalidHexColor(String)

A hex literal provided to create a Color was not RGB / RGBA

ParseInt(ParseIntError)

A string hex code was invalid as a hex literal

Raw(String)

A generic error type for use in user code when needing to construct a simple DrawError.

UnknownFont(String)

An attempt was made to use a font that had not beed registered

Xcb(XcbError)

Wrapper around XCB implementation errors for draw traits

Cairo(Error)

An attempt to use the cairo C API failed when using an XCB implementation of Draw or DrawContext

Trait Implementations

impl Debug for DrawError

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

Formats the value using the given formatter.

impl Display for DrawError

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

Formats the value using the given formatter.

impl Error for DrawError

pub fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace #53487)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
