Errors that can arise from the creation and use of LcdScreens.

Variants

Video(String)

Indicates that an error occurred when attempting to initalize the SDL video subsystem. This error is a simple wrapper around the underlying SDL error. Please consult the sdl2 documentation for more details.

WindowBuild(WindowBuildError)

Indicates that an error occurred when attempting to build the OS window for the LcdScreen. This error is a simple wrapper around the underlying SDL error. Please consult the sdl2 documentation for more details.

CanvasBuild(IntegerOrSdlError)

Indicates that an error occurred when attempting to build the canvas for the LcdScreen. This error is a simple wrapper around the underlying SDL error. Please consult the sdl2 documentation for more details.

Fill(String)

Indicates that an error occurred when attempting to fill a dot on the LcdScreen. This error is a simple wrapper around the underlying SDL error. Please consult the sdl2 documentation for more details.

WindowWidth

Indicates that the LcdScreen is too wide to be displayed. The maximum width of a screen is i32::MAX pixels. As the width of the screen is set by the number of rows of dots it has multiplied by the pixel width of each dot, one or both of those values must be reduced.

Fields

width: u32

the total width in pixels of the undisplayed screen

row: usize

the number of rows of dots of the undisplayed screen

dot_width: u32

the pixel width of the dots of the undisplayed screen

WindowHeight

Indicates that the LcdScreen is too high to be displayed. The maximum height of a screen is i32::MAX pixels. As the height of the screen is set by the number of columns of dots it has multiplied by the height of each dot, one or both of those values must be reduced.

Fields

height: u32

the total height in pixels of the undisplayed screen

col: usize

the number of columns of dots of the undisplayed screen

dot_height: u32

the pixel height of the dots of the undisplayed screen

Trait Implementations

impl Debug for LcdError

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

Formats the value using the given formatter.

impl Display for LcdError

fn fmt(&self, fmtr: &mut Formatter<'_>) -> FmtResult

Formats the value using the given formatter.

impl Error for LcdError

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.
