    pub execution_id: String,
    pub workflow_id: String,
    pub node_id: String,
    pub status: TaskStatus,

Implementations

impl Task

pub fn new( execution_id: String, workflow_id: String, node_id: String, input: NodeInput, context: ExecutionContext, ) -> Self

Create a new task

pub fn get_node(&self, storage: &Storage) -> Result<&Node>

Get the node for this task (lazy-loaded)

pub fn get_workflow(&self, storage: &Storage) -> Result<Arc<Workflow>>

Get the workflow for this task (lazy-loaded and shared)

pub fn set_workflow(&self, workflow: Arc<Workflow>) -> Result<(), Arc<Workflow>>

Pre-populate the workflow Arc to avoid lazy loading from storage This is useful when creating tasks from a workflow that’s already in memory

pub fn start(&mut self)

Mark task as running

pub fn complete(&mut self, output: NodeOutput)

Mark task as completed

pub fn fail(&mut self, error: String)

Mark task as failed

pub fn for_single_node(node: Node, input: NodeInput) -> Self

Create a task for a single node execution (no workflow context)

pub fn priority(&self) -> u64

Get priority for queue ordering (lower timestamp = higher priority)

Trait Implementations

impl Clone for Task

fn clone(&self) -> Task

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Task

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Task

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Task

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TS for Task

type WithoutGenerics = Task

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 = Task

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() -> 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() -> String

Name of this type in TypeScript, including generic parameters

fn decl_concrete() -> 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() -> String

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

fn inline() -> 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() -> String

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

fn visit_generics(v: &mut impl TypeVisitor)

where Self: 'static,

Iterates over all type parameters of this type.

fn output_path() -> Option<PathBuf>

Returns the output path to where T should be exported.
The returned path does not include the base directory from TS_RS_EXPORT_DIR.

fn visit_dependencies(v: &mut impl TypeVisitor)

where Self: 'static,

Iterates over all dependency of this type.

fn dependencies() -> Vec<Dependency>

where Self: 'static,

Resolves all dependencies of this type recursively.

fn export() -> 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() -> 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_all_to(out_dir: impl AsRef<Path>) -> Result<(), ExportError>

where Self: 'static,

Manually export this type into the given directory, together with all of its dependencies.
To export only this type, without its dependencies, use [TS::export].

fn export_to_string() -> 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.

fn default_output_path() -> Option<PathBuf>

Returns the output path to where T should be exported.
