abseil-duration-conversion-cast
|
|
===============================
|
|
|
|
Checks for casts of ``absl::Duration`` conversion functions, and recommends
|
|
the right conversion function instead.
|
|
|
|
Examples:
|
|
|
|
.. code-block:: c++
|
|
|
|
// Original - Cast from a double to an integer
|
|
absl::Duration d;
|
|
int i = static_cast<int>(absl::ToDoubleSeconds(d));
|
|
|
|
// Suggested - Use the integer conversion function directly.
|
|
int i = absl::ToInt64Seconds(d);
|
|
|
|
|
|
// Original - Cast from a double to an integer
|
|
absl::Duration d;
|
|
double x = static_cast<double>(absl::ToInt64Seconds(d));
|
|
|
|
// Suggested - Use the integer conversion function directly.
|
|
double x = absl::ToDoubleSeconds(d);
|
|
|
|
|
|
Note: In the second example, the suggested fix could yield a different result,
|
|
as the conversion to integer could truncate. In practice, this is very rare,
|
|
and you should use ``absl::Trunc`` to perform this operation explicitly instead.
