Struct GetentResolver 

pub struct GetentResolver { /* private fields */ }

Decides which getent binary name resolution spawns, hardened against PATH attacks when privileged. Built once from the CLI via GetentResolver::from_cli.

The decision is deliberately not made at construction time: a numeric-only invocation (--owner 0) never needs getent, so the trusted-directory probe — and its “getent not found” error — must not fire then. The probe runs only when a name is actually looked up.

Implementations

impl GetentResolver

pub fn from_cli(getent_path: Option<PathBuf>, privileged: bool) -> Result<Self>

Build from the parsed CLI. getent_path is an explicit --getent-path (already reduced to at most one by the caller); privileged is is_privileged. A relative --getent-path is rejected here (fail-fast) — a relative program would re-introduce a PATH/cwd lookup, defeating the point.

Trait Implementations

impl Clone for GetentResolver

fn clone(&self) -> GetentResolver

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GetentResolver

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for GetentResolver

The unprivileged, no-override default: a normal PATH search. Used by tests and as a sensible base; production builds the resolver from the CLI via GetentResolver::from_cli.

fn default() -> Self

Returns the “default value” for a type.
