Trait for producers of groups.

Required Methods

fn get_group_by_gid(&self, gid: gid_t) -> Option<Arc<Group>>

Returns a Group if one exists for the given group ID; otherwise, returns None.

fn get_group_by_name<S: AsRef<OsStr> + ?Sized>( &self, group_name: &S, ) -> Option<Arc<Group>>

Returns a Group if one exists for the given groupname; otherwise, returns None.

fn get_current_gid(&self) -> gid_t

Returns the group ID for the user running the process.

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

Returns the group name of the user running the process.

fn get_effective_gid(&self) -> gid_t

Returns the effective group id.

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

Returns the effective group name.

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.
