# Structs and Methods

|
|
# The keyword `struct` is used to define structures
|
|
# that hold multiple members:
|
|
struct Point(x:Int, y:Int):
|
|
|
|
# Methods are any function defined inside of the
|
|
# indented area below a struct definition.
|
|
|
|
# There is no implicit `self` argument, only the
|
|
# arguments you explicitly define.
|
|
func abs(p:Point -> Point):
|
|
return Point(p.x:abs(), p.y:abs())
|
|
|
|
# Constants can be declared inside of a struct's namespace:
|
|
ZERO := Point(0, 0)
|
|
|
|
# Arbitrary functions can also be defined here:
|
|
func squared_int(x:Int -> Int):
|
|
return x * x
|
|
|
|
func main():
|
|
|
|
# You can create a struct instance like this:
|
|
p := Point(x=3, y=-4)
|
|
|
|
>> p
|
|
= Point(x=???, y=???)
|
|
|
|
>> Point.ZERO
|
|
= Point(x=???, y=???)
|
|
|
|
>> p.x
|
|

|

|
