Enum JsonTreeMutateError 

pub enum JsonTreeMutateError<R, Q, E>
where
    Q: Copy + Debug,
{
    InputBudget(MeasuredBudgetError<R, Q>),
    Visitor(E),
    OutputBudget(MeasuredBudgetError<R, Q>),
}

Identifies the phase that failed during a budget-aware JSON tree mutation.

Input and output budgets are deliberately separate so callers can decide which transaction, if any, remains eligible for commit after a failure.

Type Parameters

• R - Resource identity attached to budget failures.
• Q - Quantity representation attached to budget failures.
• E - Error type returned by the mutation visitor.

Examples

use qubit_json::value::traverse::JsonTreeMutateError;

let error: JsonTreeMutateError<(), usize, &str> =
    JsonTreeMutateError::Visitor("mutation rejected");
assert!(matches!(error, JsonTreeMutateError::Visitor(_)));

Variants

InputBudget(MeasuredBudgetError<R, Q>)

The complete tree before mutation exceeded its input budget.

Tuple Fields

0: MeasuredBudgetError<R, Q>

Resource measurement for the original tree.

Visitor(E)

The caller-defined visitor failed after mutation began.

Tuple Fields

0: E

Domain error returned after the visitor began mutating the tree.

OutputBudget(MeasuredBudgetError<R, Q>)

The complete tree after mutation exceeded its output budget.

Tuple Fields

0: MeasuredBudgetError<R, Q>

Resource measurement for the mutated tree.

Trait Implementations

impl<R, Q, E> Error for JsonTreeMutateError<R, Q, E>

where Q: Copy + Debug, MeasuredBudgetError<R, Q>: Error + 'static, Self: Debug + Display,

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>)
