Enum Action 

pub enum Action<R: Renderer> {
    Event {
        parent: Option<TaskId>,
        data: R::EventData,
    },
    TaskStart {
        id: TaskId,
        parent: Option<TaskId>,
        data: R::TaskData,
    },
    TaskEnd {
        id: TaskId,
    },
    CancelAll,
}

A state change in the task tree.

Example

use trace_tally::*;

struct MyRenderer;
impl Renderer for MyRenderer {
    type EventData = String;
    type TaskData = String;
}

let mut renderer = TaskRenderer::new(MyRenderer);
renderer.update(Action::TaskStart {
    id: TaskId::from(2),
    parent: None,
    data: "my task".into(),
});
renderer.render(&mut std::io::stderr()).unwrap();

Variants

Event

A new event on an existing task (or the root if parent is None).

Fields

parent: Option<TaskId>

data: R::EventData

TaskStart

A new task has started.

If parent is None or refers to an unknown ID, the task is attached to the virtual root.

Fields

id: TaskId

parent: Option<TaskId>

data: R::TaskData

TaskEnd

A task has completed.

Fields

id: TaskId

CancelAll

Mark all pending tasks as cancelled.

Walks every task reachable from root and sets them as cancelled. Cancelled tasks still render (via TaskView::cancelled) but are flushed from the active frame on the next render, like completed tasks.
