Struct Users 

pub struct Users { /* private fields */ }

Cache of resolved user names, keyed by uid.

Lookups are cached because a scan resolves the same handful of uids thousands of times, and getpwuid_r walks the directory service each call.

Implementations

pub fn new() -> Self

pub fn name(&mut self, uid: u32) -> &str

pub fn name_of(uid: u32) -> String

Resolve without caching, for one-off use.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

Trait Implementations
