Bindings for jemalloc as an allocator

This crate provides bindings to jemalloc as a memory allocator for Rust. This crate mainly exports, one type, Jemalloc, which implements the GlobalAlloc trait and optionally the Alloc trait, and is suitable both as a memory allocator and as a global allocator.


  • Handle to the jemalloc allocator


  • Return the usable size of the allocation pointed to by ptr.
