🌌psMap.union
union of two psMaps
creates a new psMap that maps all the keys that exist either in psMap.this
or in other to the values they are mapped to. In case a key k exists in
both psMap.this and other, it will be mapped to psMap.this[k] or to other[k],
but it is undefined to which of these two.
helper to add 'psMap.this.data[l..r]' to 'a' and return the resulting map.
§addAll(a ref psMap<psMap.K, psMap.V>, at i32, sz i32, tail i32) => ref psMap<psMap.K, psMap.V>:Object
§addAll(a ref psMap<psMap.K, psMap.V>, at i32, sz i32, tail i32)
=>
ref psMap<psMap.K, psMap.V>:
Objecthelper to add 'sz' elements from 'psMap.this.data[at..at+sz]' to 'a', with
'tail' elements at indices larger or equal to 'at+sz' added recursively as
well.
