NOTE

If you want Windows support, check faccess instead.

permissions

Useful filesystem queries for file permissions:

See functions.

• is_executable
• is_readable
• is_writable
• is_removable
• is_creatable
• access_syscall supports a custom bitfield of permissions.

Examples:

use permissions::*;

fn main() -> std::io::Result<()> {
   // Functions accept `AsRef<Path>`
   assert!(is_readable("src/")?);
   assert!(is_writable("src/")?);
   assert!(is_writable("src/lib.rs")?);
   assert!(is_executable("/usr/bin/cat")?);
   assert!(is_removable("src/lib.rs")?);
   assert!(is_creatable("src/file.rs")?);

   Ok(())
}

Alternatives

• faccess - it provides Windows support and a trait-based API.
