Description
rust-analyzer version: rust-analyzer 1.90.0 (1159e78 2025-09-14)
rustc version: rustc 1.90.0 (1159e78c4 2025-09-14)
editor or extension: Zed 0.205.5
code snippet to reproduce:
#[faux::create]
struct S {
a: i32,
}
#[faux::methods]
impl S {
fn do_work(&mut self) {
let s = "abcd";
//let n = s.len();
self.a = 0;
}
}
When typing the commented line, I don't get a suggestion for len method or any other methods.
If I put semicolon in the end in advance, then it starts working.
Also if I remove macros annotations then it starts working as expected too.
