Enum DebugTraceElement 

pub enum DebugTraceElement {
    Regular {
        entrypoint: OwnedEntrypointName,
        trace_element: ContractTraceElement,
        energy_used: Energy,
        debug_trace: DebugTracker,
    },
    Debug {

        contract_address: ContractAddress,

        error: InvokeExecutionError,
        trace_elements: Vec<DebugTraceElement>,
        energy_used: Energy,
        debug_trace: DebugTracker,
    },
}

A wrapper for ContractTraceElement, which provides additional information for testing and debugging. Most notably, it contains trace elements for failures, which are normally discarded by the node.

Variants

Regular

A regular trace element with some additional data, e.g., energy usage and the entrypoint. This variant may be included in the WithFailures list of trace elements.

Fields

entrypoint: OwnedEntrypointName

The entrypoint.

trace_element: ContractTraceElement

The trace element.

energy_used: Energy

The energy used so far.

debug_trace: DebugTracker

Debug

A record of debug events emitted before the interrupt. Contract queries, such as querying account balance or exchange rates do not produce any events visible in the Regular trace elements or in the transaction outcomes, but the internal debug information is still useful for debugging.

Fields

entrypoint: OwnedEntrypointName

The entrypoint that is being executed.

address: ContractAddress

The address that is affected.

debug_trace: DebugTracker

Events emitted until the interrupt.

WithFailures

One or multiple trace elements that fail. Useful for debugging. This variant also contains additional information, such as the error, entrypoint, and energy usage.

Fields

contract_address: ContractAddress

The address of the contract which failed. This will always match the address in the last element in trace_elements if the vector isn’t empty.

entrypoint: OwnedEntrypointName

The entrypoint which failed. This will always match the address in the last element in trace_elements if the vector isn’t empty.

error: InvokeExecutionError

The error returned.

trace_elements: Vec<DebugTraceElement>

Intermediate DebugTraceElements which occurred prior to failing. These are the elements which are normally discared by the node.

energy_used: Energy

The energy used so far.

debug_trace: DebugTracker

Detailed breakdown of debug output and host calls produced so far.

Trait Implementations

impl Debug for DebugTraceElement

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

Formats the value using the given formatter.
