Step response DTO — public API representation of a step.

Examples

use ironflow_store::models::Step;
use ironflow_api::entities::StepResponse;

Fields

id: Uuid

Unique step identifier.

trace_id: Uuid

Deterministic trace ID for log correlation.

run_id: Uuid

Parent run ID.

name: String

Step name.

kind: StepKind

Step operation type.

position: u32

Execution order (0-based).

status: StepStatus

Current status.

attempt: u32

Which run attempt produced this step (1-based).

A run retried twice exposes steps with attempt 1, 2 and 3. Steps from earlier attempts are kept so a failed attempt stays inspectable.

input: Option<Value>

Input configuration.

output: Option<Value>

Step output.

error: Option<String>

Optional error message.

duration_ms: u64

Execution duration in milliseconds.

cost_usd: Decimal

Cost in USD.

input_tokens: Option<u64>

Input token count (agent steps).

output_tokens: Option<u64>

Output token count (agent steps).

created_at: DateTime<Utc>

When created.

updated_at: DateTime<Utc>

When updated.

started_at: Option<DateTime<Utc>>

When execution started.

completed_at: Option<DateTime<Utc>>

When execution completed.

dependencies: Vec<Uuid>

IDs of steps this step depends on (direct dependencies).

debug_messages: Option<Value>

Verbose conversation trace for agent steps (thinking blocks, tool calls, tool results, per-turn usage). None when verbose mode was off or the step is not an agent step.

artifacts: Vec<ArtifactResponse>

Files this step produced, downloadable through the artifact route.

Empty when the step produced none or when artifact storage is not configured on the server.

approval_deadline_at: Option<DateTime<Utc>>

When this approval gate expires, if it carries an SLA deadline.

approval_seconds_remaining: Option<i64>

Seconds left before the gate escalates. Clamped at 0, None when the step has no deadline.

approval_assignee: Option<Assignee>

Who the approval is currently assigned to.

Serialized as a prefixed string: user:{name} or group:{name}.

approval_requirement: Option<ApprovalRequirement>

Approval requirement evaluated from the gate’s approval rules when it opened. None for steps without rules.

approvals: Vec<StepApproval>

Votes cast on the approval gate so far, at most one per user.

approvals_required: Option<u32>

Distinct approvals the gate needs: the requirement’s count, 1 for an approval step without rules, None for any other step kind.

Implementations

impl StepResponse

pub fn with_dependencies(step: Step, dependencies: Vec<Uuid>) -> Self

Build a response from a step entity with pre-resolved dependencies.

Artifacts are left empty; use with_dependencies_and_artifacts when they have been fetched.

pub fn with_dependencies_and_artifacts( step: Step, dependencies: Vec<Uuid>, artifacts: Vec<ArtifactResponse>, ) -> Self

Build a response from a step entity with its dependencies and artifacts.

Trait Implementations

impl<'de> Deserialize<'de> for StepResponse

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Step> for StepResponse

fn from(step: Step) -> Self

Converts to this type from the input type.

impl Serialize for StepResponse

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
