Classes

Defined in namespace std::experimental::pmr
an abstract interface for classes that encapsulate memory resources
(class)
a thread-safe memory_resource for managing allocations in pools of different block sizes
(class)
a thread-unsafe memory_resource for managing allocations in pools of different block sizes
(class)
a special-purpose memory_resource that releases the allocated memory only when the resource is destroyed
(class)
an allocator that supports run-time polymorphism based on the memory_resource it is constructed with
(class template)
adapts an allocator into a memory_resource
(alias template)

Functions

Defined in namespace std::experimental::pmr
Comparison
compare two memory_resources
(function)
compares two allocators
(function template)
Global memory resources
returns a static program-wide memory_resource that uses the global operator new and operator delete to allocate and deallocate memory
(function)
returns a static memory_resource that performs no allocation
(function)
Default memory resource
gets the default memory_resource
(function)
sets the default memory_resource
(function)
