Enum LayoutError 

pub enum LayoutError {
    InsufficientSpace,
    InvalidConfiguration,
    PositioningFailed,
}

Error type for layout operations.

This error type covers chart layout calculations, component positioning, and space allocation operations.

Common Scenarios

• Insufficient space for chart components
• Invalid layout configuration
• Component positioning failures

Examples

use embedded_charts::prelude::*;
use embedded_charts::error::LayoutError;
use embedded_graphics::prelude::*;

// Example function that might return a LayoutError
fn check_layout_error() -> Result<(), LayoutError> {
    // This would be actual layout calculation logic
    Err(LayoutError::InsufficientSpace)
}

match check_layout_error() {
    Ok(()) => println!("Layout calculated successfully"),
    Err(LayoutError::InsufficientSpace) => println!("Viewport too small"),
    Err(LayoutError::InvalidConfiguration) => println!("Invalid layout config"),
    Err(e) => println!("Layout error: {}", e),
}

Variants

InsufficientSpace

Insufficient space for layout.

Occurs when the available viewport is too small to accommodate the chart and its components with the current configuration.

InvalidConfiguration

Invalid layout configuration.

Returned when layout parameters are invalid or conflicting, such as negative margins or impossible component arrangements.

PositioningFailed

Component positioning failed.

Occurs when individual chart components cannot be positioned within the available space, even with valid overall layout.

Trait Implementations

impl Clone for LayoutError

fn clone(&self) -> LayoutError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LayoutError

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

Formats the value using the given formatter.

impl Display for LayoutError

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

Formats the value using the given formatter.

impl Error for LayoutError

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<LayoutError> for ChartError

fn from(_error: LayoutError) -> Self

Converts to this type from the input type.

impl PartialEq for LayoutError

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