:mrdocs:

Set the value attribute of the element in this bucket having the specified `key` to the specified `value`, using the specified `equal` to compare keys. If no such element exists, insert `(key, value)`. The behavior with respect to duplicate key values in the bucket depends on the specified `scope`:

== Description

: `e_BUCKETSCOPE_ALL`:: Set `value` to every element in the bucket having `key`.:: `e_BUCKETSCOPE_FIRST`:: Set `value` to the first element found having `key`.

Return the number of elements found having `key` that had their value set. Note that, when there are multiple elements having `key`, the selection of "first" is unspecified and subject to change. Also note that specifying `e_BUCKETSCOPE_FIRST` is more performant when there is a single element in the bucket having `key`.
