How to set a value to null in languages.toml?

[ameknite]

I want to set a value to null to enable the unlimited maxLength feature for the rust-analyzer config in my languages.toml

but I cannot set it to null, I tried {} , 0, "", but nothing works.

[language.config.inlayHints]
maxLength = null

The rust analyzer manual tell this, but only works in json, how I do the same in toml?

rust-analyzer.inlayHints.maxLength (default: 25)

Maximum length for inlay hints. Set to null to have an unlimited length.

It looks like TOML doesn't support null values: toml-lang/toml#30. As a workaround you could configure that setting to a very large number.
