Struct lance_encoding::encodings::physical::bitmap::DenseBitmapScheduler

pub struct DenseBitmapScheduler { /* private fields */ }

A physical scheduler for bitmap buffers encoded densely as 1 bit per value with bit-endianess (e.g. what Arrow uses for validity bitmaps and boolean arrays)

This decoder decodes from one buffer of disk data into one buffer of memory data
