@iffyio please take a look

[iffyio]

Thanks @osipovartem! Left a minor comment otherwise the changes look good to me

[iffyio]

oh this looks like its only used once, can we inline it instead?

[osipovartem]

This will be used in the next PR
related to #1982

[iffyio]

Ah I see, but I think we can inline it in this PR and if it ends up being used in the next PR we can break it out into a function. Also heads up for the function we would want to make it either private or pub(crate) visibility wise instead of pub

[osipovartem]

Replaced duplicated code by parse_boolean_string call

Please review again

LGTM! Thanks @osipovartem!
