pub unsafe fn read<T: Copy>(name: &[u8]) -> Result<T>Expand description
Uses the null-terminated string name as key to the MALLCTL NAMESPACE and
reads its value.
ยงSafety
This function is unsafe because it is possible to use it to construct an
invalid T, for example, by passing T=bool for a key returning u8. The
sizes of bool and u8 match, but bool cannot represent all values that
u8 can.
