pub enum Either<L, R> {
Left(L),
Right(R),
}
Available on crate feature
progress
only.Expand description
An implementation of NestedProgress
showing either one or the other implementation.
Useful in conjunction with Discard
and a working implementation, making it as a form of Option<Progress>
which
can be passed to methods requiring impl Progress
.
See DoOrDiscard
for an incarnation of this.

source§fn set(&self, step: usize)
fn set(&self, step: usize)
Set the current progress to the given
step
. The cost of this call is negligible,
making manual throttling not necessary. Read moresource§fn inc_by(&self, step: usize)
fn inc_by(&self, step: usize)
Increment the current progress to the given
step
.

fn add_child( &mut self, name: impl Into<String>, ) -> <Either<L, R> as NestedProgress>::SubProgress

source§fn init(&mut self, max: Option<usize>, unit: Option<Unit>)
fn init(&mut self, max: Option<usize>, unit: Option<Unit>)
Initialize the Item for receiving progress information. Read more
source§fn max(&self) -> Option<usize>
fn max(&self) -> Option<usize>
Returns the maximum about of items we expect, as provided with the
init(…)
callsource§fn set_max(&mut self, max: Option<usize>) -> Option<usize>
fn set_max(&mut self, max: Option<usize>) -> Option<usize>
Set the maximum value to
max
and return the old maximum value.source§fn set_name(&mut self, name: String)
fn set_name(&mut self, name: 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>
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]
fn id(&self) -> [u8; 4]
Get a stable identifier for the progress instance.
Note that it could be unknown.

fn message(&self, level: MessageLevel, message: String)
source§fn info(&self, message: String)
fn info(&self, message: String)
Create a message providing additional information about the progress thus far.
source§fn show_throughput(&self, start: Instant)
fn show_throughput(&self, start: Instant)
A shorthand to print throughput information

&self,
start: Instant,
step: usize,

fn show_throughput_with( &self, start: Instant, step: usize, unit: Unit, level: MessageLevel, )
A shorthand to print throughput information, with the given step and unit, and message level.
