Errors that can occur when applying operations.

Variants

TypeMismatch

Type mismatch between expected and actual.

Fields

expected: ExpectedType

actual: String

context: String

NodeNotFound

Target node not found in the AST.

Fields

node: NodeId

SlotOccupied

Slot is already occupied.

Fields

node: NodeId

current_occupant: String

ConstraintViolation

One or more constraints were violated.

Fields

violated_constraints: Vec<ViolationDetail>

InvalidOperation

The operation is invalid for the given context.

Fields

action: String

reason: String

Trait Implementations

impl Clone for OperationError

fn clone(&self) -> OperationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OperationError

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

Formats the value using the given formatter.

impl PartialEq for OperationError

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