Function load_model_from_reader 

pub fn load_model_from_reader(
    reader: impl BufRead,
) -> Result<SvmModel, SvmError>

Load an SVM model from any buffered reader.

Uses LoadOptions::default. See load_model for the validation contract and non-goals. This is the reader-backed equivalent of LIBSVM’s svm_load_model.
