Struct WorkflowSummary 

pub struct WorkflowSummary {
    pub workflow_id: WorkflowId,
    pub workflow_type: String,
    pub status: WorkflowStatus,
    pub started_at: DateTime<Utc>,
    pub ended_at: Option<DateTime<Utc>>,
    pub parent: Option<WorkflowId>,
    pub failed_step: Option<String>,
    pub failure_reason: Option<String>,
    pub display_name: Option<String>,
    pub kind: Option<String>,
}

Lightweight projection of a workflow execution for query results.

Fields

workflow_id: WorkflowId

Workflow execution identifier.

workflow_type: String

Workflow type recorded when the execution started.

status: WorkflowStatus

Status projected from authoritative workflow history.

started_at: DateTime<Utc>

Timestamp recorded on the workflow start event.

ended_at: Option<DateTime<Utc>>

Timestamp recorded on the terminal lifecycle event, if any.

parent: Option<WorkflowId>

Parent workflow identifier for child-workflow executions, if the store has one.

failed_step: Option<String>

The step (activity type) that failed, populated ONLY for a workflow whose current-lease terminal is Event::WorkflowFailed and whose failure has a terminal activity failure to attribute it to (e.g. dev_review). This is the workflow step, never a brief id or label. None for every healthy/running/completed/cancelled workflow, so list renderers show no empty failure column for non-failed rows.

failure_reason: Option<String>

The terminal WorkflowFailed error message, populated ONLY for a workflow whose current-lease terminal is Event::WorkflowFailed. None otherwise.

display_name: Option<String>

The WORKFLOW’s operator-facing display name (#211), projected from the aion.display_name search attribute (last write wins, so a rename’s later recorded update supersedes the start-time name). A label over the UUID identity, never an address: None renders as the bare UUID.

Per workflow, not per run, unlike the rest of this summary: the recorded attribute carries no run id and the projection folds the whole history, so a continue-as-new successor’s summary carries the name its predecessor was wearing — see WorkflowSummary::from_history.

kind: Option<String>

The run’s document kind (workloop brief, listing surface): "workloop" for workloop runs, None for ordinary workflows. Projected from the aion.kind search attribute exactly like display_name — additive, with NO change to WorkflowStatus. Folded per workflow, last write wins, so every generation of a loop’s continue-as-new chain wears it.

Implementations

impl WorkflowSummary

pub fn from_history(events: &[Event]) -> Option<WorkflowSummary>

Builds a workflow summary from a workflow event history.

Returns None when the history does not contain a Event::WorkflowStarted event. The projected status and end timestamp are derived from the current run in the history, matching status_from_events. Parent linkage (aion#77) is projected from the current run’s own recorded parent_workflow_id — the child wears its parent; histories recorded before the field decode to None.

failed_step and failure_reason are populated ONLY when the current lease’s terminal event is Event::WorkflowFailed (see failure_projection); a reopened, running, completed, or cancelled workflow leaves both None.

display_name (#211) is NOT scoped that way. It is folded over the whole history by crate::display_name, last write wins, and the recorded attribute carries no run id — so it is a per-WORKFLOW label even though the rest of this summary projects the current run. Hand this a history that continued as new and the successor’s summary carries the name its predecessor was wearing, until something renames it.

Trait Implementations

impl Clone for WorkflowSummary

impl StructuralPartialEq for WorkflowSummary

impl TS for WorkflowSummary

type WithoutGenerics = WorkflowSummary

If this type does not have generic parameters, then WithoutGenerics should just be Self. If the type does have generic parameters, then all generic parameters must be replaced with a dummy type, e.g ts_rs::Dummy or ().
The only requirement for these dummy types is that EXPORT_TO must be None.

type OptionInnerType = WorkflowSummary

If the implementing type is std::option::Option<T>, then this associated type is set to T. All other implementations of TS should set this type to Self instead.

fn ident(cfg: &Config) -> String

Identifier of this type, excluding generic parameters.

fn docs() -> Option<String>

JSDoc comment to describe this type in TypeScript - when TS is derived, docs are automatically read from your doc comments or #[doc = ".."] attributes

fn name(cfg: &Config) -> String

Name of this type in TypeScript, including generic parameters

fn decl_concrete(cfg: &Config) -> String

Declaration of this type using the supplied generic arguments. The resulting TypeScript definition will not be generic. For that, see TS::decl(). If this type is not generic, then this function is equivalent to TS::decl().

fn decl(cfg: &Config) -> String

Declaration of this type, e.g. type User = { user_id: number, ... }. This function will panic if the type has no declaration.

fn inline(cfg: &Config) -> String

Formats this types definition in TypeScript, e.g { user_id: number }. This function will panic if the type cannot be inlined.

fn inline_flattened(cfg: &Config) -> String

Flatten a type declaration. This function will panic if the type cannot be flattened.

fn visit_generics(v: &mut impl TypeVisitor)

where WorkflowSummary: 'static,

Iterates over all type parameters of this type.

fn output_path() -> Option<PathBuf>

Returns the output path to where T should be exported, relative to the output directory. The returned path does not include any base directory.

fn visit_dependencies(v: &mut impl TypeVisitor)

where WorkflowSummary: 'static,

Iterates over all dependency of this type.

fn dependencies(cfg: &Config) -> Vec<Dependency>

where Self: 'static,

Resolves all dependencies of this type recursively.

fn export(cfg: &Config) -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem. To export this type together with all of its dependencies, use TS::export_all.

fn export_all(cfg: &Config) -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem, together with all of its dependencies. To export only this type, without its dependencies, use TS::export.

fn export_to_string(cfg: &Config) -> Result<String, ExportError>

where Self: 'static,

Manually generate bindings for this type, returning a String. This function does not format the output, even if the format feature is enabled.
