Generate new method
When I hover the mouse cursor over a struct or a impl, I want the light bulb to present me with "Create new method".
If I have:
struct Point {
x: i32,
y: i32,
}
And hover my mouse cursor over the "Point" (the struct keyword or the struct name), then I would get presented with the light bulb, and if I chose "Create new method", it would turn it into.
struct Point {
x: i32,
y: i32,
}
impl Point {
fn new() -> Point {
// TODO return a new Point
}
}
or perhaps even better?
struct Point {
x: i32,
y: i32,
}
impl Point {
fn new(x: i32, y: i32) -> Point {
Point { x: x, y: y }
}
}
rust-analyzer provides this already. @Xanewok @matklad considering the RA plugin is now being merged here, how should we handle cases like this?
I would say closing with "implemented with rust-analyzer backend" is probably the right call.But probably after we conclude the merge
rust-analyzer provides this already
How do I access this from vscode though? I'm not getting a light bulb or any other kind of indication that RA can do something special here.
impl<Prov> Pointer<Option<Prov>> {
fn foo() -> Self {
Pointer { /* cursor is here */ }
}
}
The only thing I know to do is delete the line, type Pointe, and then pick Pointer { ... } from the autocompletion. That generates a struct instance with all the field names written out, which is nice.
(Then also a lightbulb shows up, but only with very generic things: "extract into function", "sort methods alphabetically".)
@RalfJung the Generate new assist is only available on the definition of the struct, so you have to go to the definition and press Ctrl+. there.
Ah I see. :)
Is there a list of these magic assists somewhere, and which cursor positions trigger them? They sound really useful, but not very easy to discover.
