[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/in_mod.rs","byte_start":300,"byte_end":305,"line_start":14,"line_end":14,"column_start":14,"column_end":19,"is_primary":true,"text":[{"text":"        drop(owned);","highlight_start":14,"highlight_end":19}],"label":"move out of `owned` occurs here","suggested_replacement":null,"suggestion_applicability":null,"expansion":null},{"file_name":"tests/unstable-pass/in_mod.rs","byte_start":215,"byte_end":220,"line_start":10,"line_end":10,"column_start":26,"column_end":31,"is_primary":false,"text":[{"text":"        let mut_1 = &mut owned[0];","highlight_start":26,"highlight_end":31}],"label":"borrow of `owned` occurs here","suggested_replacement":null,"suggestion_applicability":null,"expansion":null},{"file_name":"tests/unstable-pass/in_mod.rs","byte_start":128,"byte_end":137,"line_start":7,"line_end":7,"column_start":13,"column_end":22,"is_primary":false,"text":[{"text":"        let mut owned = vec![1, 32];","highlight_start":13,"highlight_end":22}],"label":"binding `owned` declared here","suggested_replacement":null,"suggestion_applicability":null,"expansion":null},{"file_name":"tests/unstable-pass/in_mod.rs","byte_start":332,"byte_end":338,"line_start":15,"line_end":15,"column_start":25,"column_end":31,"is_primary":false,"text":[{"text":"        let undefined = *mut_1 + *mut_2;","highlight_start":25,"highlight_end":31}],"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/in_mod.rs","byte_start":220,"byte_end":220,"line_start":10,"line_end":10,"column_start":31,"column_end":31,"is_primary":true,"text":[{"text":"        let mut_1 = &mut owned[0];","highlight_start":31,"highlight_end":31}],"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/in_mod.rs:14:14\n   |\n7  |         let mut owned = vec![1, 32];\n   |             --------- binding `owned` declared here\n...\n10 |         let mut_1 = &mut owned[0];\n   |                          ----- borrow of `owned` occurs here\n...\n14 |         drop(owned);\n   |              ^^^^^ move out of `owned` occurs here\n15 |         let undefined = *mut_1 + *mut_2;\n   |                         ------ borrow later used here\n   |\nhelp: consider cloning the value if the performance cost is acceptable\n   |\n10 |         let mut_1 = &mut owned.clone()[0];\n   |                               ++++++++\n\n"}
