Buffers in Rust! - In this video I demonstrate code to read a text file into a buffer as bytes and display the number of bytes.
🟩 A buffer is typically a block of memory used for temporary storage of data. Buffers are commonly used when reading or writing data to or from sources like files, network sockets, or memory.
🟩 They help optimize I/O operations by reducing the number of system calls or memory allocations.
🟩 Most byte streams in Rust implement Read trait - it works by reading some number of bytes (1024 in this case) from a source (in this case, the "example.txt" file) and stores them in buf, which the program can then process.
! Note: the iterator will return a result, not bytes!
