Expose a read/receive method without NN_MSG option

[blabaere]

Is there a way to provide nn_recv the native buffer used by a Vec[u8], to avoid the copy ?

Yeah, that would be ideal. Nanomsg also supports true zero-copy.

In fact, this should be the default behavior of the Reader trait read function. Since it is passed a mutable slice, there must be a way to tell nanomsg to use the native underlying pointer and to remove the NN_MSG option. I think now that the read_to_end function is the only right place to use NN_MSG.

[thehydroimpulse]

Agreed!

[blabaere]

This is now done as read function of Reader trait is passing the raw pointer of the slice parameter to nanomsg.
