abseil-duration-conversion-cast¶
Checks for casts of absl::Duration
conversion functions, and recommends
the right conversion function instead.
Examples:
// 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.
