pub struct Task {
pub index: usize,
/* private fields */
}
Expand description
Unit of work arranged by a Sequencer.
Use the standard library write!
or writeln!
macros for writing the
output of a task. Additionally this type provides some methods for setting
the color of task output.
Refer to the crate-level documentation and the documentation of the Sequencer type for the recommended patterns of launching tasks.
use oqueue::{Color::Blue, Task};
fn work(task: Task) {
task.color(Blue);
writeln!(task, "hello from task #{}", task.index);
}
Fields§
§index: usize
Index of the current task. This is a sequential counter that begins at 0 and increments by 1 for each successively started task. It may be helpful in determining what work this task is responsible for performing.
This field is read-only; writing to its value will not compile.

fn is_synchronous(&self) -> bool
Returns true if and only if the underlying writer must synchronously
interact with an end user’s device in order to control colors. By
