Required Methods

fn get_user_by_uid(&self, uid: uid_t) -> Option<Arc<User>>

Returns a User if one exists for the given user ID; otherwise, returns None.

fn get_user_by_name<S: AsRef<OsStr> + ?Sized>( &self, username: &S, ) -> Option<Arc<User>>

Returns a User if one exists for the given username; otherwise, returns None.

fn get_current_uid(&self) -> uid_t

Returns the user ID for the user running the process.

fn get_current_username(&self) -> Option<Arc<OsStr>>

Returns the username of the user running the process.

fn get_effective_uid(&self) -> uid_t

Returns the effective user id.

fn get_effective_username(&self) -> Option<Arc<OsStr>>

Returns the effective username.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
