Component in std::path - Rust (original) (raw)
Enum Component
1.0.0 · Source
pub enum Component<'a> {
Prefix(PrefixComponent<'a>),
RootDir,
CurDir,
ParentDir,
Normal(&'a OsStr),
}Expand description
A single component of a path.
A Component roughly corresponds to a substring between path separators (/ or \).
This enum is created by iterating over Components, which in turn is created by the components method on Path.
§Examples
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()),
]);§1.0.0
A Windows path prefix, e.g., C: or \\server\share.
There is a large variety of prefix types, see Prefix’s documentation for more.
Does not occur on Unix.

It represents a separator that designates that a path starts from root.
§1.0.0
A reference to the current directory, i.e., ..
§1.0.0
A reference to the parent directory, i.e., ...
§1.0.0
A normal component, e.g., a and b in a/b.
This variant is the most common one, it represents references to files or directories.

Extracts the underlying OsStr slice.
§Examples
use std::path::Path;
let path = Path::new("./tmp/foo/bar.txt");
let components: Vec<_> = path.components().map(|comp| comp.as_os_str()).collect();
assert_eq!(&components, &[".", "tmp", "foo", "bar.txt"]);Converts this type into a shared reference of the (usually inferred) input type.
Converts this type into a shared reference of the (usually inferred) input type.

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
