xo-alloc2 documentation
xo-alloc2 provides:
Fast vm-aware arena allocation.
Allocates uncommitted virtual memory, and commits on demand.
When available, uses THP (Transparent Huge Pages) to mitigate pagetable pressure.
Optional GC support, with per-alloc header.
Diagnostic features:
with alloc headers: forward iterators over individual allocations
configurable guard memory between allocations.
Implemented using FOMO (faceted rust-like object model) from xo-facet
