I had a crystal clear picture of what I wanted Maps to be when we first started discussing it within OTP about two-three years ago. Calls Fun(Elem, AccIn) on successive elements A of List, starting with AccIn == Acc0. Fun/2 must return a new accumulator, which is passed to the next call. The function returns the final value of the accumulator.

When iterating over a map, the memory usage is guaranteed to be bounded no matter the size of the map. The call fails with a {badmap,Map} exception if Map is not a map. Example: Maps are considered experimental during OTP 17 and may be subject to change. The documentation below describes it being possible to use arbitrary expressions or variables as keys, this is NOT implemented in the current version of Erlang/OTP.

Erlang got a new data structure in release 17.0, the map(). This structure is a finite mapping from keys to values with a flat internal representation: a map is essentially two arrays: one of

To quote from the mail: Write a function map_search_pred(Map, Pred) that returns the first There's no builtin function in Erlang that does exactly this but it can be done with maps:fold/3 and maps:update_with/4 like this: 1> A = #{"Ala" Map :: #{Key => Value, _ => _}. find(_,_) -> erlang:nif_error(undef). %% Shadowed by erl_bif_types: maps:from_list/1.

The function takes a list of key-value tuples elements and builds a map. The associations may be in any order and both keys and values in the association may be of any term. The maps implementation that came with Erlang 17.x and 18.0 is complete, but only within the confines of the maps module. The major differences come from the syntax. Only a minimal subset of it is available: literal map declarations (# {}, # {key1 => val1, "key2" => val2}) A map Mconsists of a number of associationsand keeps an association Any term, compound or otherwise, is a viable key or value. are recognized by guard tests erlang:is_map/1.

Because Erlang maps respect Erlang sorting order, a map such as #{1.0 => true} is going to compare equal to #{1 => true}, but you won't be able to match them one against the other. Be careful, because although the content of this section is written as based on EEP-43, the actual implementation might be lagging behind! Erlang got a new data structure in release 17.0, the map().

less naïve. Specifically, we will make it run on multiple Erlang nodes, balance the load between them, and begin to make the code fault-tolerant.

Erlang映射 (Map)映射用于表示键和值的关联关系。这种关联方式是由 “#{” 与 “}” 括起来。创建一个字符串 "key" 到值 42 的映射的方法如下： 1>#{ "key"=>42}.

Returns a map iterator Iterator that can be used by maps:next/1 to traverse the key-value associations in a map. When iterating over a map, the memory usage is guaranteed to be bounded no matter the size of the map. The call fails with a {badmap,Map} exception if Map is not a map. Example: Maps are considered experimental during OTP 17 and may be subject to change. The documentation below describes it being possible to use arbitrary expressions or variables as keys, this is NOT implemented in the current version of Erlang/OTP.. Exceptions returns badarg instead of badmap, this will change in the future releases.
