parse_duration()

Duration cloe::parse_duration

(

const std::string &

fmt

)

Convert a string containing a number and a unit to a duration.

The following units are supported:

ns
us
ms
s

Will throw an exception on malformed or out-of-range input.

Note: This parse function preserves precision even for floating point numbers. For example, 0.1 is not exactly representable as a floating point number, but together with a unit, we can scale it so that it is represented exactly.
