Struct CITaskGraph 

pub struct CITaskGraph { /* private fields */ }

CI Task graph for dependency resolution and parallel execution

Implementations

impl CITaskGraph

pub fn from_ir(ir: &IntermediateRepresentation) -> Result<Self, GraphError>

Build a task graph from an IR document

Errors

Returns error if dependencies reference non-existent tasks or if the graph contains cycles.

pub fn has_cycles(&self) -> bool

Check if the graph contains cycles

pub fn task_count(&self) -> usize

Get the number of tasks in the graph

pub fn get_parallel_groups(&self) -> Result<Vec<Vec<&CITaskNode>>, GraphError>

Get tasks grouped by dependency level for parallel execution

Returns groups where all tasks in a group can execute concurrently because they have no dependencies on each other.

Errors

Returns error if topological sort fails (shouldn’t happen if cycle check passed).

pub fn compute_digests( &mut self, ir: &IntermediateRepresentation, secret_fingerprints: &HashMap<String, HashMap<String, String>>, system_salt: Option<&str>, )

Compute digests for all tasks after secret resolution

This must be called after secrets are resolved to include secret fingerprints in the digest computation.

Arguments

• ir - The IR document (for runtime lookups)
• secret_fingerprints - Map of task_id -> (secret_name -> fingerprint)
• system_salt - Optional system salt for secret HMAC

pub fn get_task(&self, id: &str) -> Option<&CITaskNode>

Get a task node by ID

pub fn task_ids(&self) -> Vec<&str>

Get all task IDs in the graph

pub fn propagate_deployment_cache_policy(&mut self) -> Vec<String>

Propagate cache_policy: disabled to tasks that transitively depend on deployment tasks

According to PRD v1.3, tasks depending on deployments should inherit cache_policy: disabled for that execution to ensure deployment ordering is always respected.

Returns

List of task IDs that had their cache policy changed

pub fn depends_on_deployment(&self, task_id: &str) -> bool

Check if a task transitively depends on any deployment task
