package circular

// Implement a circular buffer of bytes supporting both overflow-checked writes
// and unconditional, possibly overwriting, writes.
//
// We chose the provided API so that Buffer implements io.ByteReader
// and io.ByteWriter and can be used (size permitting) as a drop in
// replacement for anything using that interface.

// Define the Buffer type here.
