starkware-libs/cairo-lang v0.2.0

on GitHub

StarkNet:

• StarkNet contract compiler and StarkNet CLI (command line interface)
• @external, @view and @storage_var decorators

Cairo language:

• Remove-unused-functions optimization
• Dot operator (e.g., (x + 1).y) and the subscript operator (x[3]).
• Tuples ((2, 3, 4))
• Struct data-constructors (let t = T(x=1, y=2))
• Compare structs (assert a = b, where a and b are of type T)

Cairo architecture:

• Safe call (the Cairo CPU ensures that each call instruction returns).
