is it possible to use vertical split for :RustLsp runnables?

[ssh352]

Currently the split is a horizontal split below the code. I ctrl-w H to move the split to vertical split on the left, then I run :RustLsp runnables, it uses a horizontal split again.

Is it possible to configure rustaceanvim to use a vertical split? Thanks!

The built-in 'termopen' runnables executor is very rudimental and can't be configured.
I'm not sure (it came from rust-tools), but it may be possible to do so with the 'toggleterm' executor. See :h rustaceanvim.config and :h RustaceanToolsOpts, as well as the toggleterm docs.
