pub enum Component<'a> {
Prefix(PrefixComponent<'a>),
RootDir,
CurDir,
ParentDir,
Normal(&'a OsStr),
}
A single component of a path.
See the module documentation for an in-depth explanation of components and their role in the API.
This enum is created from iterating over the path::Components struct.
use std::path::{Component, Path};
let path = Path::new("/tmp/foo/bar.txt");
let components = path.components().collect::<Vec<_>>();
assert_eq!(&components, &[
Component::RootDir,
Component::Normal("tmp".as_ref()),
Component::Normal("foo".as_ref()),
Component::Normal("bar.txt".as_ref()),
]); Prefix(PrefixComponent<'a>)A Windows path prefix, e.g. C: or \\server\share.
Does not occur on Unix.
RootDirThe root directory component, appears after any prefix and before anything else
CurDirA reference to the current directory, i.e. .
ParentDirA reference to the parent directory, i.e. ..
Normal(&'a OsStr)A normal component, i.e. a and b in a/b
