Layout of State Variables in Storage

Statically-sized variables (everything except mapping and dynamically-sized array types) are laid out contiguously in storage starting from position ``0``. Multiple, contiguous items that need less than 32 bytes are packed into a single storage slot if possible, according to the following rules:

Due to their unpredictable size, mapping and dynamically-sized array types use a Keccak-256 hash

computation to find the starting position of the value or the array data. These starting positions are always full stack slots.

JSON Output
|
||||
===========
|
||||
|
||||
.. _storage-layout-top-level:
|
||||
|
||||
The storage layout of a contract can be requested via the :ref:`standard JSON interface <compiler-api>`. The output is a JSON object containing two keys,
|
||||
``storage`` and ``types``. The ``storage`` object is an array where each
|
||||
element has the following form:
|
||||
|
||||
|
||||
.. code::
|
||||
|
||||
|
||||
{
|
||||
"astId": 2,
|
||||
"contract": "fileA:A",
|
||||
"label": "x",
|
||||
"offset": 0,
|
||||
"slot": "0",
|
||||
"type": "t_uint256"
|
||||
}
|
||||
|
||||
where the example above is the storage layout of ``contract A { uint x; }`` from source unit ``fileA``
|
||||
and
|
||||
|
||||
- ``astId`` is the id of the AST node of the state variable's declaration
|
||||
- ``contract`` is the name of the contract including its path as prefix
|
||||
- ``label`` is the name of the state variable
|
||||
- ``offset`` is the offset in bytes within the storage slot according to the encoding
|
||||
- ``slot`` is the storage slot where the state variable resides or starts. This
|
||||
number may be very large and therefore its JSON value is represented as a
|
||||
string.
|
||||
- ``type`` is an identifier used as key to the variable's type information (described in the following)
|
||||
|
||||
The given ``type``, in this case ``t_uint256`` represents an element in
|
||||
``types``, which has the form:
|
||||
|
||||
|
||||
.. code::
|
||||
|
||||
{
|
||||
"encoding": "inplace",
|
||||
"label": "uint256",
|
||||
"numberOfBytes": "32",
|
||||
}
|
||||
|
||||
where
|
||||
|
||||
- ``encoding`` how the data is encoded in storage, where the possible values are:
|
||||
|
||||
- ``inplace``: data is laid out contiguously in storage (see :ref:`above <storage-inplace-encoding>`).
|
||||
- ``mapping``: Keccak-256 hash-based method (see :ref:`above <storage-hashed-encoding>`).
|
||||
- ``dynamic_array``: Keccak-256 hash-based method (see :ref:`above <storage-hashed-encoding>`).
|
||||
- ``bytes``: single slot or Keccak-256 hash-based depending on the data size (see :ref:`above <bytes-and-string>`).
|
||||
|
||||
- ``label`` is the canonical type name.
|
||||
- ``numberOfBytes`` is the number of used bytes (as a decimal string). Note that if ``numberOfBytes > 32`` this means that more than one slot is used.
|
||||
|
||||
Some types have extra information besides the four above. Mappings contain
|
||||
its ``key`` and ``value`` types (again referencing an entry in this mapping
|
||||
of types), arrays have its ``base`` type, and structs list their ``members`` in
|
||||
the same format as the top-level ``storage`` (see :ref:`above
|
||||
<storage-layout-top-level>`).
|
||||
|
||||
.. note ::
|
||||
The JSON output format of a contract's storage layout is still considered experimental
|
||||
and is subject to change in non-breaking releases of Solidity.
|
||||
|
||||
The following example shows a contract and its storage layout, containing
|
||||
value and reference types, types that are encoded packed, and nested types.
