Fixes #657.
This PR introduces the
SeekBuf
trait for buffers that support arbitrary lookups of memory, and a newBufCursor
struct for immutably iterating over aSeekBuf
type.SeekBuf
is strictly an opt-in trait with additional functionality over the standardBuf
trait and otherwise does not change the API of this crate.The
BufCursor
type provides compatibility to a wide range of core/std Rust features through itsIterator
implementation. It also allows recursive and non-consuming access to the full memory of a buffer that was otherwise not possible via theBuf
trait.
