/// A slice buffer holds the memory for a collection of slices.
/// The SliceBuffer object itself is meant to only hide the C-style API,
/// and won't hold the data itself. In terms of lifespan, the
/// grpc_slice_buffer ought to be kept somewhere inside the caller's objects,
/// like a transport or an endpoint.
///
/// This lifespan rule is likely to change in the future, as we may
/// collapse the grpc_slice_buffer structure straight into this class.
///
/// The SliceBuffer API is basically a replica of the grpc_slice_buffer's,
/// and its documentation will move here once we remove the C structure,
/// which should happen before the EventEngine's API is no longer
/// an experimental API.
