Jemalloc

Struct Jemalloc

pub struct Jemalloc;

Available on crate feature jemalloc only.

Expand description

Handle to the jemalloc allocator

This type implements the GlobalAllocAlloc trait, allowing usage a global allocator.

When the alloc_trait feature of this crate is enabled, it also implements the Alloc trait, allowing usage in collections.
