Used in snmalloc-rs
snmalloc-rs provides a wrapper for
microsoft/snmalloc to make it usable as a global allocator for rust.
snmalloc is a research allocator. Its key design features are:
- Memory that is freed by the same thread that allocated it does not require any synchronising operations.
- Freeing memory in a different thread to initially allocated it, does not take any locks and instead uses a novel message passing scheme to return the memory to the original allocator, where it is recycled.
- The allocator uses large ranges of pages to reduce the amount of meta-data required.
Some old benchmark results are available in the
There are three features defined in this crate:
debug: Enable the
1mib: Use the
cache-friendly: Make the allocator more cache friendly (setting
64in building the library).
snmalloc-rs add it as a dependency:
# Cargo.toml [dependencies] snmalloc-rs = "0.2"
SnMalloc as the global allocator add this to your project:
#[global_allocator] static ALLOC: snmalloc_rs::SnMalloc = snmalloc_rs::SnMalloc;
