Rust: error[E0507]: cannot move out of `self.name` which is behind a shared reference

You tried to take ownership of a value through a reference (or from a Vec/Option behind &).

Exact message you may see error[E0507]: cannot move out of `self.name` which is behind a shared referencecannot move out of index of `Vec<String>`cannot move out of borrowed contenterror[E0507]: cannot move out of a mutable referencemove occurs because has type which does not implement the `Copy` trait E0507

Meaning

Clone (self.name.clone()), borrow (&self.name), use Option::take()/mem::replace/mem::take to move out safely, or change the function to take self by value. vec[i] can't move non-Copy elements; use &vec[i] or vec.remove(i).

Common causes

  • Moving a String/Vec field out of &self
  • Moving out of vec[i]
  • Option field behind &mut self moved without take()
  • Pattern matching moving out of a reference without ref/&
  • Returning an owned value from a borrowed field

⚡ Quick fix

  1. .clone() when cheap, or return &T
  2. self.field.take() / std::mem::take(&mut self.field)
  3. match &self.x { Some(v) => ... }

Detailed fix by platform

Rust

  1. let name = std::mem::take(&mut self.name);

How to diagnose

  1. Access — Through & or &mut?
  2. Type — Copy?
  3. Fix — take/clone/borrow?
