    PanelNoParent,
    OnlyChild,

A mutation is not supported or invalid for the current state.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NoStrategy

No strategy set on the runtime.

NoFocusedPanel

No panel is focused.

FocusedNoParent

Focused panel has no parent.

ParentNotContainer

Parent is not a container node.

PanelNoParent

Panel has no parent.

OnlyChild

Panel is the only child.

SiblingsNotPanels

resize_boundary requires all siblings to be panels.

SiblingsNotGrow

resize_boundary requires all siblings to use grow constraints.

NoCollapsedSlots

No collapsed slots to uncollapse.

SlotNoSavedConstraints

Slot has no saved constraints.

MoveNotSupported

Move not supported for this layout.

Trait Implementations

impl Debug for MutationError

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

Formats the value using the given formatter.

impl Display for MutationError

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

Formats the value using the given formatter.

impl Error for MutationError

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.
