Release Notes

BurntSushi/jiff (jiff-tzdb)

v0.1.9

Compare Source

==================
This release introduces new options for controlling the precision
of fractional seconds when printing Zoned, Timestamp,
civil::DateTime or civil::Time values. This is principally exposed
via jiff::fmt::temporal::DateTimePrinter::precision, but it's also
available via the standard library's formatting machinery. For example,
if zdt is a jiff::Zoned, then format!("{zdt:.6}") will format
it into a string with microsecond precision, even if its fractional
component is zero.

Enhancements:

• #​92:
  Support setting the precision of fractional seconds when printing datetimes.

Footnotes

1. 54 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

2. No successful run was found on main (d027897) during the generation of this report, so b8a42fe was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩
