pub fn activate<N: AsRef<str>>(name: N)Expand description
Makes name the active environment.
Takes effect immediately: stores bound to the previous environment reset on their next access and reopen against this one.
A switch is not free to repeat. Backends also drop the compiled artifacts they memoized for the old environment, and on CUDA and HIP the modules those entries named stay resident, because nothing can safely unload a module a stream may still have queued work against. Switching a handful of times at startup costs a bounded amount of device memory and one recompilation per kernel; switching per request grows resident modules without bound.
