E050: You called new() on a struct that never defined one

StructName::new(...) only works if that struct actually has a .new constructor written for it somewhere. Unlike calling a regular method with a typo, there’s no “did you mean” fallback here – a struct either has a new you can call with arguments, or it doesn’t, and this error means yours doesn’t (yet).

For example, this struct never declared a .new:

struct Point {    x: int,    y: int}mut p: Point = Point::new(1, 2);   // ERROR: 'Point' has no constructor -- 'Point::new(...)' can't be called

You’ve got two good options here, depending on what you actually want:

If you want to construct it with specific starting values, write a .new for it:

fn Point.new(x: int, y: int): void {    self.x = x;    self.y = y;}

If you just want an instance with every field zeroed out and don’t need custom logic, you don’t need to write anything at all – every struct automatically gets a ::default() you can call instead:

mut p: Point = Point::default();

So if you’re seeing this error and don’t actually need custom construction logic, switching from Point::new(1, 2) to Point::default() (and then setting fields manually with p.x = 1; afterward, if needed) is often the quickest fix.
