Enum WriterBackendType 

#[non_exhaustive]
pub enum WriterBackendType {
    Feather,
    Parquet,
    External(String),
}

Streaming writer backend used to persist run data, mirroring CatalogBackendType.

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.
