Trait for writing inverted index data to underlying storage.

Required Methods

fn add_index<'life0, 'async_trait>( &'life0 mut self, name: String, null_bitmap: Bitmap, values: ValueStream, bitmap_type: BitmapType, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Adds entries to an index.

• name is the index identifier.
• null_bitmap marks positions of null entries.
• values is a stream of values and their locations, yielded lexicographically. Errors occur if the values are out of order.
• bitmap_type is the type of bitmap to encode.

fn finish<'life0, 'async_trait>( &'life0 mut self, total_row_count: u64, segment_row_count: NonZeroUsize, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Finalizes the index writing process, ensuring all data is written. total_row_count and segment_row_count is used to fill in the metadata.
