# Description This PR adds new types to `nu-path` to enforce path invariants. Namely, this PR adds: - `Path` and `PathBuf`. These types are different from, but analogous to `std::path::Path` and `std::path::PathBuf`. - `RelativePath` and `RelativePathBuf`. These types must be/contain strictly relative paths. - `AbsolutePath` and `AbsolutePathBuf`. These types must be/contain strictly absolute paths. - `CanonicalPath` and `CanonicalPathBuf`. These types must be/contain canonical paths. Operations are prohibited as necessary to ensure that the invariants of each type are upheld (needs double-checking). Only paths that are absolute (or canonical) can be easily used as / converted to `std::path::Path`s. This is to help force us to account for the emulated current working directory instead of accidentally using the current directory of the Nushell process (i.e., `std::env::current_dir`). Related to #12975 and #12976. Note that this PR uses several declarative macros, as the file / this PR would otherwise be 5000 lines long. # User-Facing Changes No major changes yet, just adds types to `nu-path` to be used in the future. # After Submitting Actually use the new path types in all our crates where it makes sense, removing usages of `std::path` types. |

This crate takes care of path handling in Nushell, such as canonicalization and component expansion, as well as other path-related utilities.
