pub unsafe fn update_mib<T>(mib: &[usize], value: T) -> Result<T>Expand description
Uses the MIB mib as key to the MALLCTL NAMESPACE and writes its value
returning its previous 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=u8 for a key expecting bool. The
sizes of bool and u8 match, but bool cannot represent all values that
u8 can.
