Collect collects [iter.Seq] into a map.

Entries returns all entry of a map as an [iter.Seq].

EntrySlice return entry slice of a map.

Filter keep those elements which match the given predicate function.

FilterMap keep those elements which match the given predicate function and map to new type elements.

ForEach iter over the map, and call the udf on each k-v pair.

Invert maps k-v to v-k, when key conflict, the back element will overwrite the previous one.

Keys return key's [iter.Seq] of a map.

KeySlice return key slice of a map.

Map call f on each k-v pair and maps to x-y pair into a new map.

MergeFunc merge many maps and solve conflict use an udf.

MergeKeep merge many maps and keep first value when conflict occurred.

MergeOverwrite merge many maps and keep last value when conflict occurred.

Values return value's [iter.Seq] of a map.

ValueSlice return value slice of a map.

MapEntry persist k-v pair of a map.
