Function tikv_jemalloc_ctl::raw::read [−][src]
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.
Safety
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.
