Structs
The following code shows basic use of a struct.
Point: struct {
x: float
y: float
}
Comma separation is optional in struct initialization and definition.
Point is thus defined as a data structure containing two float fields xand y.You can define instances of
Pointlike so:point0 := new Point {
x: 100
y: 200
}
point1: Point = new Point {
x: 1
y: 2
}
Struct fields are always mutable. You can access fields of a struct like this:
point := new Point {
x: 100
y: 100
}
point x = 20
point y = point x
Wu does not use
.for field access, because doing so would be gross.We can also implement methods on our structs. This will feel very familiar for people with Rust experience.
Vector: struct {
x: float,
y: float
}
implement Vector {
new: fun(x, y) -> Self {
Vector {
x: x,
y: y
}
}
length: fun(self) -> float {
(self x^2 + self y^2)^0.5
}
normalize: fun(self) {
len := self length()
self x /= len
self y /= len
}
}
a := Vector new(100, 100)
a normalize()
Self aliases whatever struct type you're implementing on.Last modified 4yr ago
