Macro manifest_dir_macros::exist_path [−][src]
exist_path!() { /* proc-macro */ }
Allows input an absolute path, or a relative path. (multiple components are supported) If a relative path is input, it will be relative to the CARGO_MANIFEST_DIR (a directory where your Cargo.toml
located). Returns an absolute path, and it must exist.
Multiple components can be input by using commas to separate them.
