read-progress

这个std::io::Read包装器允许你回答：“这个文件已读取了多少？”

监控从Read中读取了多少。

用法

use read_progress::ReaderWithSize;
let mut rdr = ReaderWithSize::from_file(file)?;
// ...
// ... [ perform regular reads ]
rdr.fraction()         // 0 (nothing) → 1 (everything) with how much of the file has been read

// Based on how fast the file is being read you can call:
rdr.eta()              // `std::time::Duration` with how long until it's finished
rdr.est_total_time()   // `std::time::Instant` when, at this rate, it'll be finished
