Struct Activity 

pub struct Activity { /* private fields */ }

A production operation connecting input and output representations.

Implementations

impl Activity

pub fn new( id: ActivityId, kind: ActivityKind, inputs: Vec<ActivityInput>, outputs: Vec<ActivityOutput>, ) -> Result<Self>

Creates a complete production activity and canonicalizes its edges.

An activity may have no inputs, but must produce at least one output because this model does not expose an in-progress lifecycle state.

Errors

Returns ErrorKind::InvalidArgument when edges are empty or excessive, an identical edge is duplicated, or one representation appears on both sides of the activity.

pub fn with_timing( self, started_at: Option<Timestamp>, finished_at: Option<Timestamp>, ) -> Result<Self>

Adds optional activity timing.

Errors

Returns ErrorKind::InvalidArgument when both times are present and the finish precedes the start.

pub fn with_tool(self, tool: ToolIdentity) -> Self

Adds the optional tool that performed the activity.

pub fn with_agent(self, agent: AgentIdentity) -> Self

Adds the optional agent responsible for the activity.

pub const fn id(&self) -> ActivityId

Returns the activity’s stable identity.

pub const fn kind(&self) -> &ActivityKind

Returns the extensible activity kind.

pub const fn started_at(&self) -> Option<Timestamp>

Returns the optional start time.

pub const fn finished_at(&self) -> Option<Timestamp>

Returns the optional finish time.

pub const fn tool(&self) -> Option<&ToolIdentity>

Returns the optional responsible tool.

pub const fn agent(&self) -> Option<&AgentIdentity>

Returns the optional responsible agent.

pub fn inputs(&self) -> &[ActivityInput]

Returns inputs in canonical representation/role order.

pub fn outputs(&self) -> &[ActivityOutput]

Returns outputs in canonical representation/role order.

Trait Implementations

impl Clone for Activity

fn clone(&self) -> Activity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Activity

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

Formats the value using the given formatter.

impl Eq for Activity

impl PartialEq for Activity

fn eq(&self, other: &Activity) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
