API Reference — pma/resources/DefaultMemoryResource

class DefaultMemoryResource : public MemoryResource

A MemoryResource that delegates directly to malloc/free.

Why this exists

DefaultMemoryResource gives pma containers a MemoryResource-compatible fallback that behaves exactly like ordinary heap allocation, so code that doesn't need arena pooling or alignment guarantees can still participate in the same allocator abstraction as code that does.

Relationships

  • MemoryResource — base interface DefaultMemoryResource implements.
  • AlignedMemoryResource / ArenaMemoryResource — sibling resources with stricter alignment or pooled-allocation behavior.
