Expand description

Metadata describing a column in a file

This is typically created by reading the metadata section of a Lance file

Fields§

§index: u32

The index of the column in the file

§page_infos: Vec<Arc<PageInfo>>

The metadata for each page in the column

§buffer_offsets_and_sizes: Vec<(u64, u64)>

File positions and their sizes of the column-level buffers
