Data types

Not every Python data type is useful for smart contracts. For this reason, Baretta limits the data types to the list below.

Type	Description
`None`	No value
`bool`	True or false
`int64`	Signed 64-bit integer. This is the default for integers
`uint64`	Unsigned 64-bit integer
`uint128`	Unsigned 128-bit integer
`uint256`	Unsigned 256-bit integer
`str`	Text
`bytes`	Raw bytes
`list`	A list of values of one type. See Lists and dicts
`dict`	A map of keys to values. See Lists and dicts
`pointer` (`ptr`)	A reference to a value. See Baretta Rules
`function`	A function
`class`	A class
`module`	A module
`Lookup`	The result of an operation that can fail. See Lookup

An integer written without a type is int64 by default.

Details about all additional types will be provided when everything is stable and maybe there will be additional types in the future.

No try and except

Baretta removes try and except, because smart contracts do not need them. Use Lookup to handle errors instead.
