pub fn float_to_weight(f: f64) -> (u32, u32)Expand description
Convert a floating-point weight in the range (0.0,1.0) to a pair of weights
that can be used with Union and similar.
The first return value is the weight corresponding to f; the second
return value is the weight corresponding to 1.0 - f.
This call does not make any guarantees as to what range of weights it may
produce, except that adding the two return values will never overflow a
u32. As such, it is generally not meaningful to combine any other weights
with the two returned.
ยงPanics
Panics if f is not a real number between 0.0 and 1.0, both exclusive.
