| `begin` overloads
| xref:bsl/vectorBase-0b2/capacity.adoc[`capacity`] 
| Return the capacity of this vector, i.e., the maximum number of elements for which resizing is guaranteed not to trigger a reallocation.
| xref:bsl/vectorBase-0b2/cbegin.adoc[`cbegin`] 
| Return an iterator providing non‐modifiable access to the first element in this vector, and the past‐the‐end iterator if this vector is empty.

| `data` overloads
| xref:bsl/vectorBase-0b2/empty.adoc[`empty`] 
| Return `true` if this vector has size 0, and `false` otherwise.
