Trait Implementations

impl Default for Fake

fn default() -> Self

Returns the “default value” for a type.

impl System for Fake

fn read(&self, path: &Path) -> Option<String>

fn exists(&self, path: &Path) -> bool

fn list(&self, path: &Path) -> Vec<String>

fn link(&self, path: &Path) -> Option<PathBuf>

fn run(&self, command: &[&str]) -> Option<(bool, String)>

A command’s success and standard output; None when it cannot run.

fn resolve(&self, _: &str) -> Result<Vec<String>, String>

The addresses a host name resolves to, within a few seconds.

fn space(&self, path: &Path) -> Option<(u64, u64)>

Free and total bytes of the file system holding a path.

fn owner(&self, path: &Path) -> Option<u32>

The owner’s user id.

fn is_link(&self, path: &Path) -> bool

Whether the path itself is a symbolic link.

fn canonical(&self, path: &Path) -> Option<PathBuf>

The path with every link resolved.

fn user(&self) -> (u32, u32, PathBuf)

fn on_path(&self, tool: &str) -> bool

fn processes(&self) -> Vec<String>

Names of running processes.
