Mapping Types
=============
Mapping types use the syntax ``mapping(KeyType => ValueType)`` and variables
of mapping type are declared using the syntax ``mapping(KeyType => ValueType) VariableName``.
The ``KeyType`` can be any
built-in value type, ``bytes``, ``string``, or any contract or enum type. Other user-defined
or complex types, such as mappings, structs or array types are not allowed.
``ValueType`` can be any type, including mappings, arrays and structs.
Mapping types use the syntax ``mapping(KeyType KeyName? => ValueType ValueName?)`` and variables of
mapping type are declared using the syntax ``mapping(KeyType KeyName? => ValueType ValueName?)
VariableName``. The ``KeyType`` can be any built-in value type, ``bytes``, ``string``, or any
contract or enum type. Other user-defined or complex types, such as mappings, structs or array types
are not allowed. ``ValueType`` can be any type, including mappings, arrays and structs. ``KeyName``
and ``ValueName`` are optional (so ``mapping(KeyType => ValueType)`` works as well) and can be any
valid identifier that is not a type.
You can think of mappings as `hash tables <https://en.wikipedia.org/wiki/Hash_table>`_, which are virtually initialised
such that every possible key exists and is mapped to a value whose

These restrictions are also true for arrays and structs that contain mappings.
You can mark state variables of mapping type as ``public`` and Solidity creates a

If ``ValueType`` is a value type or a struct, the getter returns ``ValueType``.

If ``ValueType`` is a value type or a struct, the getter returns ``ValueType`` with

The example below is a simplified version of an

``_allowances`` is an example of a mapping type inside another mapping type.
In the example below, the optional ``KeyName`` and ``ValueName`` are provided for the mapping.
It does not affect any contract functionality or bytecode, it only sets the ``name`` field
for the inputs and outputs in the ABI for the mapping's getter.
