Enum DegradationAction 

pub enum DegradationAction {
    FallbackRender,
    ReusePreviousLayout,
    ErrorPlaceholder,
    SkipFrame,
    DropInput,
    Shutdown,
}

What the runtime should do when an error occurs.

The runtime inspects this to decide whether to retry, fall back to a simpler rendering mode, or shut down gracefully.

Variants

FallbackRender

Use fallback rendering (ASCII borders, no styling, etc.).

ReusePreviousLayout

Reuse the previous frame’s layout — do not recompute.

ErrorPlaceholder

Replace the widget with an error placeholder.

SkipFrame

Skip the current frame entirely.

DropInput

Drop the malformed input and continue processing.

Shutdown

The error is unrecoverable — shut down gracefully.

Trait Implementations

impl Clone for DegradationAction

fn clone(&self) -> DegradationAction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DegradationAction

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

Formats the value using the given formatter.

impl Display for DegradationAction

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

Formats the value using the given formatter.

impl PartialEq for DegradationAction

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