Crate pth

Module :: pth

Collection of algorithms and structures to handle paths properly.

All functions in the crate don’t touch file system, but only process paths.

Type AbsolutePath

The AbsolutePath type ensures that paths are absolute, which helps reduce issues and maintenance costs associated with relative paths. Relative paths can be problematic as they introduce additional variables and complexities, making code analysis, integration, refactoring, and testing more difficult. By using absolute paths, software architecture can be improved, similar to how avoiding global variables can enhance code quality. It is recommended to use relative paths only at the outskirts of an application.

Trait AsPath

This trait is used to avoid redundant allocation of memory by providing a reference to a Path. It is implemented only for types that can either be referenced or are references to Path itself. Unlike TryIntoPath, it does not allocate memory on the heap. However, TryIntoPath is implemented for a wider range of types because it is not restricted from allocating memory. Unlike AsRef< Path >, AsPath is implemented for a wider number of types, including those that are not directly convertible to a Path using AsRef. This is because AsPath is designed to provide a more flexible interface for path-like types, accommodating various representations that can logically be treated as paths.

Trait TryIntoPath

This trait is used to convert any path-like type into an owned PathBuf. Unlike TryIntoCowPath, it always returns an owned PathBuf, so there is no need to differentiate between borrowed and owned paths at runtime. Unlike AsPath, it is implemented for a wider range of path-like types, similar to TryIntoCowPath.

Trait TryIntoCowPath

This trait is designed to avoid redundant memory allocation. Unlike TryIntoPath, it does not allocate memory on the heap if it’s not necessary. Unlike AsPath, it is implemented for a wider number of path-like types, similar to TryIntoPath. The drawback is the necessity to differentiate borrowed and owned paths at runtime.

Functions

• canonicalize
  Returns the canonical, absolute form of the path with all intermediate components normalized and symbolic links resolved. This function does not touch fs.
• change_ext
  Replaces the existing path extension with the provided extension.
• ext
  Extracts the extension from the given path.
• exts
  Extracts multiple extensions from the given path.
• is_glob
  Determines if a given path string contains unescaped glob pattern characters.
• join_paths
  Joins a list of file system paths into a single absolute path.
• normalize
  Normalizes a given filesystem path by syntactically removing occurrences of . and properly handling .. components.
• path_common
  Finds the common directory path among a collection of paths.
• path_relative
  Computes the relative path from one path to another.
• rebase
  Rebase the file path relative to a new base path, optionally removing a common prefix.
• unique_folder_name
  Generates a unique folder name using the current system time, process ID, thread ID, and an internal thread-local counter.
• without_ext
  Extracts the parent directory and file stem (without extension) from the given path.
