pub fn from_arrow2<'de, T, A>(fields: &[Field], arrays: &'de [A]) -> Result<T>Expand description
Deserialize items from the given arrow2 arrays (requires one of the
arrow2-* features)
The type should be a list of records (e.g., a vector of structs). To
deserialize items encoding single values consider the
Items wrapper.
