Function toml::to_string_pretty

pub fn to_string_pretty<T>(value: &T) -> Result<String, Error>
where
    T: Serialize + ?Sized,

Serialize the given data structure as a “pretty” String of TOML.

This is identical to to_string except the output string has a more “pretty” output. See Serializer::pretty for more details.

To serialize TOML values, instead of documents, see ValueSerializer.
