Struct PathScanner 

pub struct PathScanner { /* private fields */ }

Walks directories (usually from $PATH) looking for executable files by name. Caches the directory list so repeated lookups during a single discovery pass don’t re-read the env var.

Implementations

impl PathScanner

pub fn from_env() -> Self

Build a scanner from the current process $PATH. Empty on platforms where PATH is unset.

pub fn from_dirs(dirs: Vec<PathBuf>) -> Self

pub fn dirs(&self) -> &[PathBuf]

pub fn find_first(&self, name: &str) -> Option<PathBuf>

First executable entry matching name, walking directories in $PATH order. Skips unreadable directories silently.
