Memory management 🦀
Memory management styles • Manually allocate / free memory (seg
fault / double free) • Garbage Collector (Ruby, Python, Golang, Java, Erlang, c) • Ownership / Borrowing (Rust only as far as I know)
Rust brings to language design and compile time the memory
management By using Ownership and Borrowing
Ownership Rules 1. Each value in Rust is owned by
variable. 2. When the owner goes out of scope, the value will be deallocated. 3. There can be Only ONE owner at a time.
1. Each value in rust is owned by a variable
2. When the owner goes out of scope the value
will deallocated
2. When the owner goes out of scope the value
will deallocated
3. There can only one owner at a time
This avoids double free in compile time 2. When the
owner goes out of scope the value will deallocated
