Enum RenderError 

pub enum RenderError {
    DrawingFailed,
    TextRenderingFailed,
    ClippingFailed,
    ColorConversionFailed,
}

Error type for rendering operations.

This error type covers low-level rendering operations including drawing primitives, text rendering, and color operations.

Common Scenarios

• Drawing operation failures
• Text rendering issues
• Color conversion problems
• Clipping operation failures

Examples

use embedded_charts::prelude::*;
use embedded_charts::error::RenderError;

// Example function that might return a RenderError
fn draw_something() -> Result<(), RenderError> {
    // This would be actual rendering logic
    Err(RenderError::DrawingFailed)
}

match draw_something() {
    Ok(()) => println!("Drawing completed successfully"),
    Err(RenderError::DrawingFailed) => println!("Failed to draw"),
    Err(RenderError::ColorConversionFailed) => println!("Invalid color"),
    Err(e) => println!("Render error: {}", e),
}

Variants

DrawingFailed

Drawing operation failed.

Generic error for drawing operations that fail due to display driver issues or invalid drawing parameters.

TextRenderingFailed

Text rendering failed.

Occurs when text cannot be rendered, typically due to font issues, invalid characters, or display limitations.

ClippingFailed

Clipping operation failed.

Returned when clipping regions cannot be established or when clipping operations fail.

ColorConversionFailed

Color conversion failed.

Occurs when color values cannot be converted between different color spaces or pixel formats.

Trait Implementations

impl Clone for RenderError

fn clone(&self) -> RenderError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RenderError

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

Formats the value using the given formatter.

impl Display for RenderError

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

Formats the value using the given formatter.

impl Error for RenderError

Available on crate feature std only.

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.

impl From<RenderError> for ChartError

fn from(_error: RenderError) -> Self

Converts to this type from the input type.

impl PartialEq for RenderError

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

Tests for self and other values to be equal, and is used by ==.

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

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