A drop-in GlobalAlloc implementation using tcmalloc from gperftools.
Requires Rust 1.28+
extern crate tcmalloc;
use tcmalloc::TCMalloc;
#[global_allocator]
static GLOBAL: TCMalloc = TCMalloc;Also note that you can only define one global allocator per application.
By default this crate expects to link to a system-installed tcmalloc. To build the bundled copy of tcmalloc, enable the "bundled" feature. Note the caveats about profiling and libunwind/libgcc on 64-bit linux — they are not built by this crate, and tcmalloc will silently link to versions of both that can cause profiling deadlocks.
