TaskStatus

Enum TaskStatus 

Source
#[repr(usize)]
pub enum TaskStatus { Pending = 0, Running = 1, Succeeded = 2, Failed = 3, Panicked = 4, Cancelled = 5, Dropped = 6, }
Expand description

Observable lifecycle status for a submitted task.

#[repr(usize)] assigns stable discriminants 0..TASK_STATUS_COUNT for internal compact state-machine encoding.

Variants§

§

Pending = 0

The task has been accepted but has not started running.

§

Running = 1

The task has started running.

§

Succeeded = 2

The task completed successfully.

§

Failed = 3

The task returned its own error value.

§

Panicked = 4

The task panicked while running.

§

Cancelled = 5

The task was explicitly cancelled before producing a value.

§

Dropped = 6

The accepted runner-side completion endpoint was abandoned before producing an explicit terminal value.

Implementations§

Source§

impl TaskStatus

Source

pub const fn is_done(self) -> bool
