Trait Implementations§

impl Progress for Discard

§

type SubProgress = Discard

The type of progress returned by add_child().
source§

fn add_child( &mut self, _name: impl Into<String> ) -> <Discard as Progress>::SubProgress

Adds a new child, whose parent is this instance, with the given name. Read more
source§

fn add_child_with_id( &mut self, _name: impl Into<String>, _id: [u8; 4] ) -> <Discard as Progress>::SubProgress

Adds a new child, whose parent is this instance, with the given name and id. Read more
source§

fn init(&mut self, _max: Option<usize>, _unit: Option<Unit>)

Initialize the Item for receiving progress information. Read more
source§

fn set(&mut self, _step: usize)

Set the current progress to the given step. The cost of this call is negligible, making manual throttling not necessary. Read more
source§

fn set_max(&mut self, _max: Option<usize>) -> Option<usize>

Set the maximum value to max and return the old maximum value.
source§

fn step(&self) -> usize

Returns the current step, as controlled by inc*(…) calls
source§

fn inc_by(&mut self, _step: usize)

Increment the current progress to the given step. The cost of this call is negligible, making manual throttling not necessary.
source§

fn set_name(&mut self, _name: impl Into<String>)

Set the name of the instance, altering the value given when crating it with add_child(…) The progress is allowed to discard it.
source§

fn name(&self) -> Option<String>

Get the name of the instance as given when creating it with add_child(…) The progress is allowed to not be named, thus there is no guarantee that a previously set names ‘sticks’.
source§

fn id(&self) -> [u8; 4]

Get a stable identifier for the progress instance. Note that it could be unknown.
source§

fn message(&mut self, _level: MessageLevel, _message: impl Into<String>)

Create a message of the given level and store it with the progress tree. Read more
source§

fn counter(&self) -> Option<Arc<AtomicUsize>>

If available, return an atomic counter for direct access to the underlying state. Read more
source§

fn unit(&self) -> Option<Unit>

Returns the (cloned) unit associated with this Progress
source§

fn max(&self) -> Option<usize>

Returns the maximum about of items we expect, as provided with the init(…) call
source§

fn inc(&mut self)

Increment the current progress to the given 1. The cost of this call is negligible, making manual throttling not necessary.
source§

fn info(&mut self, message: impl Into<String>)

Create a message providing additional information about the progress thus far.
source§

fn done(&mut self, message: impl Into<String>)

Create a message indicating the task is done successfully
source§

fn fail(&mut self, message: impl Into<String>)

Create a message indicating the task failed
source§

fn show_throughput(&mut self, start: Instant)

A shorthand to print throughput information
source§

fn show_throughput_with( &mut self, start: Instant, step: usize, unit: Unit, level: MessageLevel )

A shorthand to print throughput information, with the given step and unit, and message level.
