Module stream_loader 

Structs

CsvReadOptions

Options controlling how a CSV stream is parsed.

StreamCsvLoader

Advanced stream-based CSV loader with string interning

Functions

collect_column_names

Compute the ordered union of object keys across the first sample_size records. Order of first occurrence is preserved so the column layout is stable. Non-object records are skipped.

detect_delimiter_from_path

Pick a default delimiter from a path’s extension.

load_csv_from_reader

Simple wrapper for loading CSV without advanced features. Defaults to comma delimiter; for other delimiters use load_csv_from_reader_with_opts.

load_csv_from_reader_with_opts

As load_csv_from_reader, but honouring caller-supplied CsvReadOptions (delimiter, headers).

load_json_from_reader

Load JSON data from any Read source into a DataTable.

parse_delimiter_arg

Parse a user-supplied delimiter string into a single byte.

parse_json_records

Parse JSON content as either a JSON array of objects or JSONL (newline-delimited JSON, one object per line). The format is detected by peeking at the first non-whitespace byte: [ starts an array, anything else is parsed line-by-line.

resolve_delimiter

Resolve which delimiter to use for a given path.
