How to reproduce the issue

1. Create a Rust project with this code:

fn bar(x: usize) -> usize {
    return x + 321;
}

fn baz(y: usize) -> usize {
    return y - 321;
}

fn main() {
    let foo = bar(123);
    println!("Hello, world! {}", foo);
}

2. Execute: :RustLsp ssr bar($a) ==>> baz($a)

Expected behaviour

bar(123) gets replaced with baz(123).

Actual behaviour

Error executing vim.schedule lua callback: ...inpac/opt/rustaceanvim/lua/rustaceanvim/commands/ssr.lua:13: Could not execute request to server: Parse error: Cannot find delimiter `=
=>>`
stack traceback:
        [C]: in function 'error'
        ...inpac/opt/rustaceanvim/lua/rustaceanvim/commands/ssr.lua:13: in function 'handler'
        ...w/Cellar/neovim/0.9.4/share/nvim/runtime/lua/vim/lsp.lua:1393: in function ''
        vim/_editor.lua: in function <vim/_editor.lua:0>

The minimal config used to reproduce this issue.

Default config should trigger the issue.

I never could get this feature working with rust-tools either, so the bug might likely got inherited from it.

Also: SSR works under VSCode with rust-analyzer.
