Crate which

which

A Rust equivalent of Unix command which(1).

Example:

To find which rustc executable binary is using:

use which::which;
use std::path::PathBuf;

let result = which("rustc").unwrap();
assert_eq!(result, PathBuf::from("/usr/bin/rustc"));

Structs

• CanonicalPath
  An owned, immutable wrapper around a PathBuf containing the canonical path of an executable.
• Noop
  A handler for non-fatal errors which does nothing with them.
• Path
  An owned, immutable wrapper around a PathBuf containing the path of an executable.
• WhichConfig
  A wrapper containing all functionality in this crate.

Enums

• Error
• NonFatalError

Traits

• NonFatalErrorHandler
  Defines what should happen when a nonfatal error is encountered. A nonfatal error may represent a problem, but it doesn’t necessarily require which to stop its search.

Functions

• which
  Find an executable binary’s path by name.
• which_all
  Find all binaries with binary_name using cwd to resolve relative paths.
• which_all_global
  Find all binaries with binary_name ignoring cwd.
• which_global
  Find an executable binary’s path by name, ignoring cwd.
• which_in
  Find binary_name in the path list paths, using cwd to resolve relative paths.
• which_in_all
  Find all binaries with binary_name in the path list paths, using cwd to resolve relative paths.
• which_in_global
  Find all binaries with binary_name in the path list paths, ignoring cwd.
• which_re
  Find all binaries matching a regular expression in a the system PATH.
• which_re_in
  Find all binaries matching a regular expression in a list of paths.
