lib.rs:

This crate provides safe access to glibc's malloc_info function. See the malloc_info(3) page for details on that function.

Example

let info = malloc_info().expect("malloc_info");
println!("{:#?}", info);

Caveats

malloc_info is a glibc-specific function and is not available on all platforms. This crate will not work on platforms where malloc_info is not available.

malloc_info will only report heap statistics for the glibc heap. If your program uses a different heap implementation, for example by #[global_allocator] or by using a different libc, malloc_info will not report statistics for that heap.
