Struct cursive::utils::ProgressReader
[−]
[src]
pub struct ProgressReader<R: Read> { // some fields omitted }
Wrapper around a Read
that reports the progress made.
Used to monitor a file downloading or other slow IO task in a progress bar.
Methods
impl<R: Read> ProgressReader<R>
[src]
fn new(counter: Counter, reader: R) -> Self
Creates a new ProgressReader
around reader
.
counter
will be updated with the number of bytes read.
You should make sure the progress bar knows how many bytes should be received.
fn deconstruct(self) -> (R, Counter)
Unwraps this ProgressReader
, returning the reader and counter.
