TableMetadata
The character set used to convert input bytes into a string when reading CSV data or vice versa when writing CSV.
The separator for columns.
The separator for columns. Typically this is comma.
Base class for metadata attached to Table.
Idea is that client code can extend this trait and piggyback whatever extraneous data to Table instances.
One example is the details of the CSV format used. They are convenient to keep with the Table data in case user needs to save a modified version of the original CSV file from which the data was read from.
Another use for this metadata mechanism is during the process of autodetecting details of the CSV format by DetectingTableReader.
This trait has two values that TableReader can use directly.
For more complex format detection heuristics, this can be inherited and extended with values that a more custom detection algorithm then tries to detect.
