Enum Schema 

#[non_exhaustive]
pub enum Schema {
    AvroSchema(Box<AvroSchema>),
    ArrowSchema(Box<ArrowSchema>),
}

The schema for the read. If read_options.selected_fields is set, the schema may be different from the table schema as it will only contain the selected fields.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

AvroSchema(Box<AvroSchema>)

Output only. Avro schema.

ArrowSchema(Box<ArrowSchema>)

Output only. Arrow schema.
