Struct oqueue::Task

pub struct Task {
    pub index: usize,
    /* private fields */
}

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.

Implementations

impl Task

pub fn bold(&self)

Set output to appear in bold uncolored.

pub fn color(&self, color: Color)

Set output to appear in color (not bold).

pub fn bold_color(&self, color: Color)

Set output to appear bold and colored.

pub fn reset_color(&self)

Set output to non-bold uncolored.

Trait Implementations

impl Clone for Task

fn clone(&self) -> Task

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Task

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

Formats the value using the given formatter.

impl Write for Task

fn write(&mut self, b: &[u8]) -> Result<usize>

Write a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_all(&mut self, buf: &[u8]) -> Result<()>

Attempts to write an entire buffer into this writer.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<()>

Writes a formatted string into this writer, returning any error encountered.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn by_ref(&mut self) -> &mut Selfwhere Self: Sized,

Creates a “by reference” adapter for this instance of Write.

impl WriteColor for Task

fn supports_color(&self) -> bool

Returns true if and only if the underlying writer supports colors.

fn set_color(&mut self, spec: &ColorSpec) -> Result<()>

Set the color settings of the writer.

fn reset(&mut self) -> Result<()>

Reset the current color settings to their original settings.

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 default, this always returns false.
