Struct ColumnChunkMetaDataBuilder

pub struct ColumnChunkMetaDataBuilder(ColumnChunkMetaData);

Builder for ColumnChunkMetaData

This builder is used to create a new column chunk metadata or modify an existing one.

Example

let column_chunk_metadata = get_column_chunk_metadata();
// create a new builder from existing column chunk metadata
let builder = ColumnChunkMetaDataBuilder::from(column_chunk_metadata);
// clear the statistics:
let column_chunk_metadata: ColumnChunkMetaData = builder
  .clear_statistics()
  .build()
  .unwrap();
