Example of a simple allocator

help
1

Hi,

I am learning Rust and want to write my own memory allocator.
Are there examples of how to do this - I am looking for bare bones example - how to construct an object after allocating memory. My understanding is that there is no placement new type facility - so the only way is to construct a struct and copy it to the heap memory?

Thanks and Regards
Dibyendu

You could check out the wee_alloc crate, which is often used in Rust WASM projects.

jenga is a bump allocator I wrote some time ago.
Designed for fast allocations that would be placed on the stack in C.
