PauMAVA / cargo-ramdisk

Create target folder as a RAMdisk for faster Rust compilation.

cargo-ramdisk

This crate is only supported for unix like systems! cargo-ramdisk creates a ramdisk at the target folder of your project for ridiculously faster compilation times.

This is achieved without root permisions by linking your target folder to a temporary folder in /dev/shm in your unix like OS. This location is rw for all users and is mounted in virtual memory as a tmpfs.

Install

cargo install cargo-ramdisk
