Struct NoResolver 

pub struct NoResolver;

Resolver for callers without a search path (tests, policy check without state).

Trait Implementations

impl Clone for NoResolver

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NoResolver

impl Debug for NoResolver

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

Formats the value using the given formatter.

impl Default for NoResolver

fn default() -> Self

Returns the “default value” for a type.

impl PathResolver for NoResolver

fn resolve(&self, _path: &str) -> Option<String>

The path path really refers to, or None when it is the same path or cannot be resolved. Paths that do not exist yet resolve through their deepest existing ancestor, so a new file written into a symlinked directory still resolves to where it would land.

fn read_dir(&self, _dir: &str) -> Vec<String>

The names in the directory dir (a normalised absolute path), without . and ..; empty when it is not a directory or cannot be read. Used only to expand an unquoted glob operand as the shell would (crate::expand). Without a filesystem nothing is listed, and the operand stays literal, as a glob that matches nothing does in bash.

impl ProgramResolver for NoResolver

fn resolve(&self, _program: &str) -> Option<String>

Absolute path program would run from, or None if it is not found.

fn pinned(&self, _program: &str) -> Option<String>

Path recorded for program when the kernel was installed, if any.
