Enum AnimationError 

pub enum AnimationError {
    InvalidDuration,
    AnimationNotFound,
    SchedulerFull,
    InterpolationError,
    InvalidState,
}

Error type for animation operations.

This error type is only available when the “animations” feature is enabled. It covers all animation-related operations including animation scheduling, interpolation, and state management.

Common Scenarios

• Invalid animation duration
• Animation scheduler at capacity
• Interpolation failures
• Invalid animation state transitions

Examples

use embedded_charts::prelude::*;
use embedded_charts::error::AnimationError;

// Example function that might return an AnimationError
fn start_animation() -> Result<u32, AnimationError> {
    // This would be actual animation logic
    Err(AnimationError::InvalidDuration)
}

match start_animation() {
    Ok(animation_id) => println!("Animation started: {}", animation_id),
    Err(AnimationError::InvalidDuration) => println!("Duration must be positive"),
    Err(AnimationError::SchedulerFull) => println!("Too many active animations"),
    Err(e) => println!("Animation error: {}", e),
}

Variants

InvalidDuration

Invalid duration specified.

Occurs when animation duration is zero, negative, or exceeds maximum allowed duration.

AnimationNotFound

Animation with specified ID was not found.

Returned when trying to access or modify an animation that doesn’t exist or has already completed.

SchedulerFull

Animation scheduler is full.

Occurs when trying to start a new animation but the scheduler has reached its maximum capacity.

InterpolationError

Error occurred during interpolation.

Returned when interpolation between animation keyframes fails, typically due to incompatible data types or invalid values.

InvalidState

Animation state is invalid.

Occurs when an animation operation is attempted on an animation in an inappropriate state (e.g., trying to pause a completed animation).

Trait Implementations

impl Clone for AnimationError

fn clone(&self) -> AnimationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnimationError

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

Formats the value using the given formatter.

impl Display for AnimationError

Available on crate feature animations only.

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

Formats the value using the given formatter.

impl Error for AnimationError

Available on crate features animations and 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<AnimationError> for ChartError

Available on crate feature animations only.

fn from(error: AnimationError) -> Self

Converts to this type from the input type.

impl PartialEq for AnimationError

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