Struct TaskGraph 

pub struct TaskGraph { /* private fields */ }

A fine-grained task dependency graph built from the project graph.

Expands project-level dependencies into target-level task dependencies, resolving local and upstream (^) dependency references.

Implementations

impl TaskGraph

pub fn build( project_graph: &ProjectGraph, target: &TargetName, ) -> Result<Self, TaskGraphError>

Build a task graph from a project graph for the given target.

This expands the project-level DAG into a fine-grained task-level DAG, resolving all depends_on references in each target configuration.

pub fn ready_tasks(&self) -> Vec<&TaskId>

Get all tasks that are ready to execute.

pub fn mark_complete( &mut self, task_id: &TaskId, ) -> Result<Vec<TaskId>, TaskGraphError>

Mark a task as complete and return the tasks that became ready.

pub fn mark_running(&mut self, task_id: &TaskId) -> Result<(), TaskGraphError>

Mark a task as running.

pub fn state(&self, task_id: &TaskId) -> Option<TaskState>

Get the state of a task.

pub fn tasks(&self) -> impl Iterator<Item = &TaskId>

Get all tasks in the graph.

pub fn dependencies_of(&self, task_id: &TaskId) -> Option<&HashSet<TaskId>>

Get the direct dependencies of a task.

pub fn len(&self) -> usize

Get the number of tasks in the graph.

pub fn is_empty(&self) -> bool

Returns true if the graph has no tasks.

pub fn all_completed(&self) -> bool

Check if all tasks are completed.

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

Formats the value using the given formatter.
