WebbIt does not help when reading very large amounts at once, or reading just one or a few times. It also provides no advantage when reading from a source that is already in memory, like a Vec. When the BufReader is dropped, the contents of its buffer will be discarded. Creating multiple instances of a BufReader on the same stream can cause ... WebbThe BufReader struct adds buffering to any reader. It can be excessively inefficient to work directly with a Read instance. For example, every call to read on TcpStream results in a system call. A BufReader performs large, infrequent reads on the underlying Read and maintains an in-memory buffer of the results. Examples Webb6 maj 2024 · having different implementations of a trait for Vec and Box< [u8]> is useful an immutable opaque blob of bytes is a Box< [u8]>. a Vec represents a mutable buffer or a list of u8 that may or may not be bytes. dvc94ch closed this as completed on Aug 25, 2024 Sign up for free to join this conversation on GitHub .
