Implementations§
source§impl DataFile
impl DataFile
sourcepub fn content_type(&self) -> DataContentType
pub fn content_type(&self) -> DataContentType
Get the content type of the data file (data, equality deletes, or position deletes)
sourcepub fn file_format(&self) -> DataFileFormat
pub fn file_format(&self) -> DataFileFormat
Get the file format of the file (avro, orc or parquet).
sourcepub fn record_count(&self) -> u64
pub fn record_count(&self) -> u64
Get the record count in the data file.
sourcepub fn file_size_in_bytes(&self) -> u64
pub fn file_size_in_bytes(&self) -> u64
Get the file size in bytes.
sourcepub fn column_sizes(&self) -> &HashMap<i32, u64>
pub fn column_sizes(&self) -> &HashMap<i32, u64>
Get the column sizes. Map from column id to the total size on disk of all regions that store the column. Does not include bytes necessary to read other columns, like footers. Null for row-oriented formats (Avro)
sourcepub fn value_counts(&self) -> &HashMap<i32, u64>
pub fn value_counts(&self) -> &HashMap<i32, u64>
Get the columns value counts for the data file. Map from column id to number of values in the column (including null and NaN values)
sourcepub fn null_value_counts(&self) -> &HashMap<i32, u64>
pub fn null_value_counts(&self) -> &HashMap<i32, u64>
Get the null value counts of the data file. Map from column id to number of null values in the column
sourcepub fn nan_value_counts(&self) -> &HashMap<i32, u64>
pub fn nan_value_counts(&self) -> &HashMap<i32, u64>
Get the nan value counts of the data file. Map from column id to number of NaN values in the column
sourcepub fn lower_bounds(&self) -> &HashMap<i32, Datum>
pub fn lower_bounds(&self) -> &HashMap<i32, Datum>
Get the lower bounds of the data file values per column. Map from column id to lower bound in the column serialized as binary.
sourcepub fn upper_bounds(&self) -> &HashMap<i32, Datum>
pub fn upper_bounds(&self) -> &HashMap<i32, Datum>
Get the upper bounds of the data file values per column. Map from column id to upper bound in the column serialized as binary.
sourcepub fn key_metadata(&self) -> &[u8] ⓘ
pub fn key_metadata(&self) -> &[u8] ⓘ
Get the Implementation-specific key metadata for the data file.
sourcepub fn split_offsets(&self) -> &[i64]
pub fn split_offsets(&self) -> &[i64]
Get the split offsets of the data file. For example, all row group offsets in a Parquet file.
sourcepub fn equality_ids(&self) -> &[i32]
pub fn equality_ids(&self) -> &[i32]
Get the equality ids of the data file. Field ids used to determine row equality in equality delete files. null when content is not EqualityDeletes.
sourcepub fn sort_order_id(&self) -> Option<i32>
pub fn sort_order_id(&self) -> Option<i32>
Get the sort order id of the data file. Only data files and equality delete files should be written with a non-null order id. Position deletes are required to be sorted by file and position, not a table order, and should set sort order id to null. Readers must ignore sort order id for position delete files.
