Struct prodash::progress::DoOrDiscard

pub struct DoOrDiscard<T>(_);

An implementation of Progress which can be created easily from Option<impl Progress>.

Implementations

impl<T: Progress> DoOrDiscard<T>

pub fn into_inner(self) -> Option<T>

Obtain either the original Progress implementation or None.

pub fn take(&mut self) -> Option<T>

Take out the implementation of Progress and replace it with Discard.

Trait Implementations

impl<T> From<Option<T>> for DoOrDiscard<T> where
    T: Progress, 

fn from(p: Option<T>) -> Self

Performs the conversion.

impl<T> Progress for DoOrDiscard<T> where
    T: Progress, 

type SubProgress = DoOrDiscard<T::SubProgress>

The type of progress returned by add_child().

fn add_child(&mut self, name: impl Into<String>) -> Self::SubProgress

Adds a new child, whose parent is this instance, with the given name.

fn init(&mut self, max: Option<usize>, unit: Option<Unit>)

Initialize the Item for receiving progress information.

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.

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

Returns the (cloned) unit associated with this Progress

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

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

fn step(&self) -> usize

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

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.

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.

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’.

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

Create a message of the given level and store it with the progress tree.

fn inc(&mut self)

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

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

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

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

Create a message indicating the task is done successfully

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

Create a message indicating the task failed

fn show_throughput(&mut self, start: Instant)

A shorthand to print throughput information

fn show_throughput_with(&mut self, start: Instant, step: Step, unit: Unit)

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