Subject: 29.0.50; `M-x rust-run' is invoking `save-some-buffers'
Date: Wed, 16 Nov 2022 19:36:42 +0530

I added a new task to my configured org file (tasks.org) by invoking
org-capture. This makes changes to tasks.org and it remains unsaved
until I explicitly save it. But I haven't saved it yet.

After adding the task I returned to the rust-mode buffer where I was
working. After making changes in my program I pressed `C-c C-c' to
invoke `rust-run'.

=> Emacs asks me to save tasks.org

i.e. it invokes `save-some-buffers'.

This could be a bug in `rust-mode'.

Doesn't it make more sense to report this to the rust-mode developers?
 I don't think I see what we can do about this in Emacs itself.

`rust-run' invokes `compile', which runs `save-some-buffers'. You
can control that with:

    compilation-ask-about-save is a variable defined in `loaddefs.el'.

    Its value is t

    Non-nil means <f8> asks which buffers to save before compiling.
    Otherwise, it saves all modified buffers without asking.

I guess you could ask the `rust-mode' developers to bind that to nil,
but the default setting has saved me on numerous occasions.
