Crate which

Expand description

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"));

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.

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.

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.
