}Expand description
Cast to a primitive numeric type using as.
AsPrim converts any primitive numeric type to any other,
using the regular cast operator as.
use asprim::AsPrim;
// Compute the mean value using f64 then cast back
fn mean<P>(data: &[P]) -> P
where P: AsPrim
{
let mut sum = 0.;
for elt in data {
sum += elt.as_f64();
}
sum /= data.len() as f64;
sum.as_()
}
fn pi<P: AsPrim>() -> P {
3.1415926535897932384626433.as_()
}Rust Version
Requires Rust 1.26 or later due to supporting as_u128
