The volume of tokens an offer wants in exchange of the full volume of promised (or given) tokens.
Note, that we also refer to a taker's wants (and gives). When not given from the context, we specify the viewpoint by referring to
takerGives). This is done, for instance, in the naming of the parameters for a marker order.
When considering a specific offer, note that from the point of view of a taker,
wants for an offer must be met by a specific
takerGives. Do note, an offer can be taken partially (see Maker Partial Fill).
For instance, if an offer
wants 2 USDC, that must be met by a
takerGives of 2 USDC.
