符合STL的内存分配器库

Question

I need to use a map , with keys as uint32_t and values as Meshes . I want the meshes to be layed out in contigous memory for performance, as they will be accessed very often in succession.

I am wondering what memory-allocator libraries are available that provides the following aswell;

• Allocates to contigous memory space
• Preferably handles fragmentation of said memory space
• As fast as possible and as little additional features as possible besides what I mentioned

I've looked at boost, but it dosn't seem to provide what I'm looking for.

(Reason I'm not using vector is that the container will grow and shrink alot, and I prefer to have a uint32_t as the identifier for a mesh )

Thanks
