I've reproduced this with latest master:

~/Source/Emacs/emacs/src/emacs -Q ~/MoreSource/Rust/hello/src/main.rs
-f rust-ts-mode -f eglot

where main.rs is the provided snippet.

Pressing C-M-i with point after 'len' yields the error.

The error only happens in partial-completion is in the completion-styles
variable, so a workaround is to remove partial-completion from
completion-styles, at least in Eglot enabled buffers.

I will look now for the underlying cause.
