abseil-duration-unnecessary-conversion
|
||
|
|
======================================
|
||
|
|
|
||
|
|
Finds and fixes cases where ``absl::Duration`` values are being converted to
|
||
|
|
numeric types and back again.
|
||
|
|
|
||
|
|
Examples:
|
||
|
|
|
||
|
|
.. code-block:: c++
|
||
|
|
|
||
|
|
// Original - Conversion to double and back again
|
||
|
|
absl::Duration d1;
|
||
|
|
absl::Duration d2 = absl::Seconds(absl::ToDoubleSeconds(d1));
|
||
|
|
|
||
|
|
// Suggestion - Remove unnecessary conversions
|
||
|
|
absl::Duration d2 = d1;
|
||
|
|
|
||
|
|
|
||
|
|
// Original - Conversion to integer and back again
|
||
|
|
absl::Duration d1;
|
||
|
|
absl::Duration d2 = absl::Hours(absl::ToInt64Hours(d1));
|
||
|
|
|
||
|
|
// Suggestion - Remove unnecessary conversions
|
||
|
|
absl::Duration d2 = d1;
|
||
|
|
|
||
|
|
Note: Converting to an integer and back to an ``absl::Duration`` might be a
|
||
|
|
truncating operation if the value is not aligned to the scale of conversion.
|
||
|
|
In the rare case where this is the intended result, callers should use
|
||
|
|
``absl::Trunc`` to truncate explicitly.
