Structs§

LimitReader: Pure implementation for LimitReader to restrict number of bytes can be read Useful when you want to read stream but want to end early no matter what
LimitSeekerReader: An AsyncRead + AsyncSeek wrapper It supports limit the bytes can be read. Typically used when you want to read a specific segments from a file
UndoReader: Undo reader supports unread(&u8) Useful when you are doing serialization/deserialization where you need to put data back (undo the read) You can use UndoReader as if it is a normal AsyncRead Additionally, UndoReader supports a limit as well. It would stop reading after limit is reached (EOF) Example:

EhRead: Enhanced Reader for std::io::Read It provides convenient methods for exact reading without throwing error It allow you to send it to writer
StreamObserver: Observe a stream’s operation when user code is not involved. For example: When you call EhRead.stream_to function, and you may want to calculate the checksum (SHA1, SHA256 or MD5 along the way, you can observe the stream copy using the observer)
