Struct unc_vm_engine::universal::LimitedMemoryPool

source · 
pub struct LimitedMemoryPool { /* private fields */ }
Expand description

The pool of preallocated memory maps for storing the code.

This pool cannot grow and will only allow up to a number of code mappings that were specified at construction time.

However it is possible for the mappings inside to grow to accomodate larger code.
