Detailed Description

This memory resource tries to allocate with several upstream resources and returns the first succesful one.

Constructor & Destructor Documentation

vecmem::coalescing_memory_resource::coalescing_memory_resource ( std::vector< std::reference_wrapper< memory_resource > > && upstreams )

explicit

Constructs the coalescing memory resource.

Note: The memory resources passed to this constructed are given in order of decreasing priority. That is to say, the first one is tried first, then the second, etc.

Parameters

[in] upstreams The upstream memory resources to use.

bool vecmem::details::memory_resource_base::do_is_equal ( const memory_resource & other ) const

overrideprotectednoexceptinherited

Compare the equality of *this memory resource with another.

Parameters

other The other memory resource to compare with
