Trait Implementations

impl Debug for AptAcquireProgress

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

Formats the value using the given formatter.

fn default() -> AptAcquireProgress

Returns the “default value” for a type.

impl DynAcquireProgress for AptAcquireProgress

fn pulse_interval(&self) -> usize

Used to send the pulse interval to the apt progress class.

Pulse Interval is in microseconds.

Example: 1 second = 1000000 microseconds.

Apt default is 500000 microseconds or 0.5 seconds.

The higher the number, the less frequent pulse updates will be.

Pulse Interval set to 0 assumes the apt defaults.

fn hit(&mut self, item: &ItemDesc)

Called when an item is confirmed to be up-to-date.

Prints out the short description and the expected size.

fn fetch(&mut self, item: &ItemDesc)

Called when an Item has started to download

Prints out the short description and the expected size.

fn done(&mut self, _item: &ItemDesc)

Called when an item is successfully and completely fetched.

We don’t print anything here to remain consistent with apt.

fn start(&mut self)

Called when progress has started.

Start does not pass information into the method.

We do not print anything here to remain consistent with apt. lastline length is set to 0 to ensure consistency when progress begins.

fn stop(&mut self, owner: &AcqTextStatus)

Called when progress has finished.

Stop does not pass information into the method.

prints out the bytes downloaded and the overall average line speed.

fn fail(&mut self, item: &ItemDesc)

Called when an Item fails to download.

Print out the ErrorText for the Item.

fn pulse(&mut self, status: &AcqTextStatus, owner: &PkgAcquire)

Called periodically to provide the overall progress information

Draws the current progress. Each line has an overall percent meter and a per active item status meter along with an overall bandwidth and ETA indicator.
