Function absolute

pub fn absolute(path: impl AsRef<Path>) -> Result<PathBuf>

Return the absolute and normalized path without accessing the filesystem.

Unlike fs::canonicalize, do not follow symlinks.

This function does not access the filesystem. Therefore it can behave differently from the kernel or other library functions in corner cases. For example:

• On some systems with symlink support, foo/bar/.. and foo can be different as seen by the kernel, if foo/bar is a symlink. This function always returns foo in this case.
• On Windows, the official normalization rules are much more complicated. See https://github.com/rust-lang/rust/pull/47363#issuecomment-357069527. For example, this function cannot translate “drive relative” path like “X:foo” to an absolute path.

Return an error if std::env::current_dir() fails or if this function fails to produce an absolute path.
