openbim-step 0.7.0

Added

• parse_parallel_with(input, options, threads): parses the data section
  on several threads and returns exactly what parse_with returns -- the
  same exchange, the same diagnostics in the same order, the same error.
  Slices start at guessed record boundaries; each slice's parser must land
  exactly on its end offset, otherwise (a guess inside a string, comment or
  damaged record, or any error) the file is parsed sequentially, so errors
  and edge cases always come from the sequential parser. On seven IFC
  files (18-109 MB) 8 threads parse 3-5x faster than one; 16 threads with
  mimalloc reach 600-1000 MB/s. The worst case is one extra sequential
  parse. Parse small files with parse_with.
• parse_events_borrowed: the same event stream as parse_events_with
  (events, order, diagnostics, errors), with text as Cow<'a, str> borrowed
  from the input wherever it needs no rewriting -- names, numbers,
  enumerations, binaries, and strings without escapes or quotes. Names keep
  their source case (the owned API upper-cases them). A consumer that
  converts every value into its own model allocates once per value instead
  of twice.

Changed

• InstanceId stores ids of up to 22 digits inline (every u64 fits), so
  a parse no longer allocates once per id and reference. Equality, hashing,
  ordering, Debug and Display are unchanged; longer ids still work.
• String decoding copies an escape-free body once instead of scanning and
  re-appending it, and number and name values are built without a second
  UTF-8 validation pass.
• Faster tokenizing, output unchanged: string bodies jump to the next \ or
  ' instead of testing every byte for a print directive; whitespace is only
  checked for a directive or comment when it is followed by \ or /;
  numbers, ids and names without ignored controls are borrowed from the input
  without a second scan. On six real IFC exports (18-109 MB) the tokenizer
  runs at 407-541 MB/s, up from 183-317, and a full parse is 1.1-1.4x
  faster. Every token, record, diagnostic and error span is identical to
  0.6.2 on 800 real and 3,000 generated files.
• New dependency: memchr (vectorized byte search).
