Struct deltachat::imex::ProgressReader
source · struct ProgressReader<R> {
inner: R,
read: usize,
file_size: usize,
last_progress: usize,
context: Context,
}
Expand description
Reader that emits progress events as bytes are read from it.
Fields§
§inner: R
Wrapped reader.
read: usize
Number of bytes successfully read from the internal reader.
file_size: usize
Total size of the backup .tar file expected to be read from the reader. Used to calculate the progress.
last_progress: usize
Last progress emitted to avoid emitting the same progress value twice.
context: Context
Context for emitting progress events.
