#[unsafe(no_mangle)]pub static malloc_conf: &[u8]Expand description
Provides the process-wide jemalloc startup configuration.
Jemalloc reads this symbol during allocator initialization, which can occur
before main. The NUL-terminated options tune the cache and decay
thresholds. CPU-affine arenas, metadata huge pages and background thread
settings are requested only on the platforms whose jemalloc provides them.
