Variants

Contract(ItemContract)

A contract, abstract contract, interface, or library definition: contract Foo is Bar, Baz { ... }

Enum(ItemEnum)

An enum definition: enum Foo { A, B, C }

Error(ItemError)

An error definition: error Foo(uint256 a, uint256 b);

Event(ItemEvent)

An event definition: event Transfer(address indexed from, address indexed to, uint256 value);

Function(ItemFunction)

A function, constructor, fallback, receive, or modifier definition: function helloWorld() external pure returns(string memory);

Import(ImportDirective)

An import directive: import "foo.sol";

Pragma(PragmaDirective)

A pragma directive: pragma solidity ^0.8.0;

Struct(ItemStruct)

A struct definition: struct Foo { uint256 bar; }

Udt(ItemUdt)

A user-defined value type definition: type Foo is uint256;

Using(UsingDirective)

A using directive: using { A, B.mul as * } for uint256 global;

Variable(VariableDefinition)

A state variable or constant definition: uint256 constant FOO = 42;
