pub unsafe fn read_mib<T: Copy>(mib: &[usize]) -> Result<T>Expand description
Uses the MIB mib as key to the MALLCTL NAMESPACE and reads its value.
The name_to_mib API translates a string of the key (e.g. arenas.nbins)
to a mib (Management Information Base).
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.
