Enum PaneError 

#[non_exhaustive]
pub enum PaneError {
    PanelNotFound(PanelId),
    InvalidConstraint(Box<str>),
    NodeNotFound(NodeId),
    InvalidTree(Box<str>),
    InvalidViewport(Box<str>),

}

Errors arising from layout operations on panels and nodes.

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.

PanelNotFound(PanelId)

A panel ID does not exist in the tree.

InvalidConstraint(Box<str>)

A constraint value is invalid (NaN, negative, mutually exclusive).

NodeNotFound(NodeId)

A node ID does not exist in the arena.

InvalidTree(Box<str>)

The tree structure is invalid or incomplete.

InvalidViewport(Box<str>)

Viewport dimensions are invalid (NaN, negative, infinite).

InvalidMutation(Box<str>)

A mutation is not supported for the current strategy.

SequenceOutOfBounds(usize, usize)

A sequence index is out of bounds.

Trait Implementations

impl Debug for PaneError

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

Formats the value using the given formatter.

impl Display for PaneError

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

Formats the value using the given formatter.

impl Error for PaneError

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.
