The rust-scudo crate contains Rust bindings for the Scudo hardened allocator.

This repository contains three crates: scudo, scudo-sys and scudo-proc-macros. The scudo crate contains an idiomatic Rust interface for Scudo. The latter scudo-sys crate contains raw C to Rust FFI bindings and the scudo-proc-macro crate contains a procedural macro to allow the configuration of the Scudo allocator.

Scudo is a dynamic user-mode memory allocator, or heap allocator, designed to be resilient against heap-related vulnerabilities (such as heap-based buffer overflow, use after free, and double free) while maintaining performance.

For more information on the allocator, take a look at the following resources:
