You understood it correctly! With `Read` you consumed the bytes on the first read. On the second attempt it returns EOF and thus the `None`. https://doc.rust-lang.org/std/io/trait.Read.html#impl-Read-2 says ``` Read is implemented for &[u8] by copying from the slice. Note that reading updates the slice to point to the yet unread part. The slice will be empty when EOF is reached. ``` If you want to `read` the same data twice you need to `reset` the source. This is what the `Seek` trait gives you. -- This is an automated message from the Apache Git Service.
