Documentation is missing lines from code snippets

[wildework]

I'm getting completion results with missing lines from documentation code blocks.

rust-analyzer version: rust-analyzer version: 0.3.2086-standalone (7106cd3be 2024-08-25)

rustc version: rustc 1.80.1 (3f5fd8dd4 2024-08-06)

editor or extension: Manually LSP server requests but same behavior with VS Code Version: 1.92.2.

code snippet to reproduce:

fn main() {
    // Place cursor at the end of ...by and the completion suggestion will include incorrect documentation.
    u16::from_le_by
}

The generated documentation has the full snippets. Also, the same as the official docs

let value = u16::from_le_bytes([0x34, 0x12]);
assert_eq!(value, 0x1234);

and

fn read_le_u16(input: &mut &[u8]) -> u16 {
    let (int_bytes, rest) = input.split_at(std::mem::size_of::<u16>());
    *input = rest;
    u16::from_le_bytes(int_bytes.try_into().unwrap())
}

Whereas rust-analyzer generates the first block as empty code and the second one with two lines with the rest missing.

Here's the LSP server completion response JSON.

},

This is known, the cause is that r-a can't yet expand macros in inert attributes (closing it as t here are bunch of issues regarding this already)

Thanks! Perhaps you could link to the other issues that refer to this issue? I looked but couldn't find them. @Veykril
