[INFO] [stdout] {"$message_type":"diagnostic","message":"cannot move out of `owned` because it is borrowed","code":{"code":"E0505","explanation":"A value was moved out while it was still borrowed.\n\nErroneous code example:\n\n```compile_fail,E0505\nstruct Value {}\n\nfn borrow(val: &Value) {}\n\nfn eat(val: Value) {}\n\nfn main() {\n    let x = Value{};\n    let _ref_to_val: &Value = &x;\n    eat(x);\n    borrow(_ref_to_val);\n}\n```\n\nHere, the function `eat` takes ownership of `x`. However,\n`x` cannot be moved because the borrow to `_ref_to_val`\nneeds to last till the function `borrow`.\nTo fix that you can do a few different things:\n\n* Try to avoid moving the variable.\n* Release borrow before move.\n* Implement the `Copy` trait on the type.\n\nExamples:\n\n```\nstruct Value {}\n\nfn borrow(val: &Value) {}\n\nfn eat(val: &Value) {}\n\nfn main() {\n    let x = Value{};\n\n    let ref_to_val: &Value = &x;\n    eat(&x); // pass by reference, if it's possible\n    borrow(ref_to_val);\n}\n```\n\nOr:\n\n```\nstruct Value {}\n\nfn borrow(val: &Value) {}\n\nfn eat(val: Value) {}\n\nfn main() {\n    let x = Value{};\n\n    let ref_to_val: &Value = &x;\n    borrow(ref_to_val);\n    // ref_to_val is no longer used.\n    eat(x);\n}\n```\n\nOr:\n\n```\n#[derive(Clone, Copy)] // implement Copy trait\nstruct Value {}\n\nfn borrow(val: &Value) {}\n\nfn eat(val: Value) {}\n\nfn main() {\n    let x = Value{};\n    let ref_to_val: &Value = &x;\n    eat(x); // it will be copied here.\n    borrow(ref_to_val);\n}\n```\n\nFor more information on Rust's ownership system, take a look at the\n[References & Borrowing][references-and-borrowing] section of the Book.\n\n[references-and-borrowing]: https://doc.rust-lang.org/book/ch04-02-references-and-borrowing.html\n"},"level":"error","spans":[{"file_name":"tests/unstable-pass/on_fn.rs","byte_start":212,"byte_end":217,"line_start":10,"line_end":10,"column_start":10,"column_end":15,"is_primary":true,"text":[{"text":"    drop(owned);","highlight_start":10,"highlight_end":15}],"label":"move out of `owned` occurs here","suggested_replacement":null,"suggestion_applicability":null,"expansion":null},{"file_name":"tests/unstable-pass/on_fn.rs","byte_start":139,"byte_end":144,"line_start":6,"line_end":6,"column_start":22,"column_end":27,"is_primary":false,"text":[{"text":"    let mut_1 = &mut owned[0];","highlight_start":22,"highlight_end":27}],"label":"borrow of `owned` occurs here","suggested_replacement":null,"suggestion_applicability":null,"expansion":null},{"file_name":"tests/unstable-pass/on_fn.rs","byte_start":60,"byte_end":69,"line_start":3,"line_end":3,"column_start":9,"column_end":18,"is_primary":false,"text":[{"text":"    let mut owned = vec![1, 32];","highlight_start":9,"highlight_end":18}],"label":"binding `owned` declared here","suggested_replacement":null,"suggestion_applicability":null,"expansion":null},{"file_name":"tests/unstable-pass/on_fn.rs","byte_start":240,"byte_end":246,"line_start":11,"line_end":11,"column_start":21,"column_end":27,"is_primary":false,"text":[{"text":"    let undefined = *mut_1 + *mut_2;","highlight_start":21,"highlight_end":27}],"label":"borrow later used here","suggested_replacement":null,"suggestion_applicability":null,"expansion":null}],"children":[{"message":"consider cloning the value if the performance cost is acceptable","code":null,"level":"help","spans":[{"file_name":"tests/unstable-pass/on_fn.rs","byte_start":144,"byte_end":144,"line_start":6,"line_end":6,"column_start":27,"column_end":27,"is_primary":true,"text":[{"text":"    let mut_1 = &mut owned[0];","highlight_start":27,"highlight_end":27}],"label":null,"suggested_replacement":".clone()","suggestion_applicability":"MachineApplicable","expansion":null}],"children":[],"rendered":null}],"rendered":"error[E0505]: cannot move out of `owned` because it is borrowed\n  --> tests/unstable-pass/on_fn.rs:10:10\n   |\n3  |     let mut owned = vec![1, 32];\n   |         --------- binding `owned` declared here\n...\n6  |     let mut_1 = &mut owned[0];\n   |                      ----- borrow of `owned` occurs here\n...\n10 |     drop(owned);\n   |          ^^^^^ move out of `owned` occurs here\n11 |     let undefined = *mut_1 + *mut_2;\n   |                     ------ borrow later used here\n   |\nhelp: consider cloning the value if the performance cost is acceptable\n   |\n6  |     let mut_1 = &mut owned.clone()[0];\n   |                           ++++++++\n\n"}
