Enum StructuredColumnType 

pub enum StructuredColumnType {
    Bytes,
    List(ListConfig),
}

Variants

Bytes

List(ListConfig)

Implementations

impl StructuredColumnType

pub fn list_element_transform<F>( config: ListConfig, transform: F, ) -> impl Fn(Option<Bytes>) -> Result<Option<Bytes>> + Send + Sync + 'static

where F: Fn(Bytes) -> Result<Bytes> + Send + Sync + 'static,

Adapt an element transform into a raw List-column schema transform.

The returned callback can be registered on writers, readers, or standalone compactors. It preserves null/empty lists, element order/count, and original expiration timestamps, without filtering expired elements or applying caps. config.preserve_element_ttl must match the source and target List encoding; the other config fields do not affect this adapter.
