Cargo and Rustc Can't seem to find the alloc crate

[BinaryAura]

I've been trying to learn more about the internals of rust by implementing data structures. I've been following this article, but it calls for using heap::allocate() rustc says heap is unresolved and I found that the heap module is in the alloc crate but, Cargo can't find it, unlike core, and rustc, says the 'alloc' is unresolved.

The article you mention hasn't been updated in a while, the functions you are looking for are in the std::alloc module.
