{"message":"unresolved import `matrix`","code":{"code":"E0432","explanation":"An import was unresolved.\n\nErroneous code example:\n\n```compile_fail,E0432\nuse something::Foo; // error: unresolved import `something::Foo`.\n```\n\nIn Rust 2015, paths in `use` statements are relative to the crate root. To\nimport items relative to the current and parent modules, use the `self::` and\n`super::` prefixes, respectively.\n\nIn Rust 2018, paths in `use` statements are relative to the current module\nunless they begin with the name of a crate or a literal `crate::`, in which\ncase they start from the crate root. As in Rust 2015 code, the `self::` and\n`super::` prefixes refer to the current and parent modules respectively.\n\nAlso verify that you didn't misspell the import name and that the import exists\nin the module from where you tried to import it. Example:\n\n```\nuse self::something::Foo; // Ok.\n\nmod something {\n pub struct Foo;\n}\n# fn main() {}\n```\n\nIf you tried to use a module from an external crate and are using Rust 2015,\nyou may have missed the `extern crate` declaration (which is usually placed in\nthe crate root):\n\n```edition2015\nextern crate core; // Required to use the `core` crate in Rust 2015.\n\nuse core::any;\n# fn main() {}\n```\n\nIn Rust 2018 the `extern crate` declaration is not required and you can instead\njust `use` it:\n\n```edition2018\nuse core::any; // No extern crate required in Rust 2018.\n# fn main() {}\n```\n"},"level":"error","spans":[{"file_name":"src/mandel.rs","byte_start":31,"byte_end":37,"line_start":2,"line_end":2,"column_start":5,"column_end":11,"is_primary":true,"text":[{"text":"use matrix::Matrix;","highlight_start":5,"highlight_end":11}],"label":"use of undeclared crate or module `matrix`","suggested_replacement":null,"suggestion_applicability":null,"expansion":null}],"children":[],"rendered":"\u001b[0m\u001b[1m\u001b[38;5;9merror[E0432]\u001b[0m\u001b[0m\u001b[1m: unresolved import `matrix`\u001b[0m\n\u001b[0m \u001b[0m\u001b[0m\u001b[1m\u001b[38;5;12m--> \u001b[0m\u001b[0msrc/mandel.rs:2:5\u001b[0m\n\u001b[0m \u001b[0m\u001b[0m\u001b[1m\u001b[38;5;12m|\u001b[0m\n\u001b[0m\u001b[1m\u001b[38;5;12m2\u001b[0m\u001b[0m \u001b[0m\u001b[0m\u001b[1m\u001b[38;5;12m| \u001b[0m\u001b[0muse matrix::Matrix;\u001b[0m\n\u001b[0m \u001b[0m\u001b[0m\u001b[1m\u001b[38;5;12m| \u001b[0m\u001b[0m \u001b[0m\u001b[0m\u001b[1m\u001b[38;5;9m^^^^^^\u001b[0m\u001b[0m \u001b[0m\u001b[0m\u001b[1m\u001b[38;5;9muse of undeclared crate or module `matrix`\u001b[0m\n\n"}
