is_executable

Is there an executable file at the given path?

A small helper function which determines whether or not the given path points to an executable file. If there is no file at the given path, or the file is not executable, then false is returned. When there is a file and the file is executable, then true is returend.

Answering this question is OS specific: some operating systems (Windows) do not distinguish between executable and non-executable file permissions. On such OSes, if there is a file at the given path, then true is returned.

The API comes in two flavors:

1. An extension trait to add an is_executable method on std::path::Path and std::fs::Permissions:

   ```rust use is_executable::IsExecutable; use std::fs; use std::path::Path;

   let path = Path::new("some/path/to/a/file");

   // Determine if path is executable. if path.isexecutable() { println!("The path is executable!"); } else { println!("The path is _not executable!"); }

   // Determine if some std::fs::Metadata's std::fs::Permissions are // executable.

   let _foo = || -> ::std::io::Result<()> {

   if fs::metadata("some/path")?.permissions().isexecutable() { println!("The permissions are executable!"); } else { println!("The permissions are _not executable!"); }

   Ok(())

   };

   ```

2. For convenience, a standalone is_executable function, which takes any AsRef<Path>:

   ```rust use isexecutable::isexecutable; use std::path::Path;

   let path = Path::new("some/path/to/a/file");

   if isexecutable(&path) { println!("The path is executable!"); } else { println!("The path is _not executable!"); } ```
