Struct std::path::PrefixComponent

pub struct PrefixComponent<'a> { /* private fields */ }

A structure wrapping a Windows path prefix as well as its unparsed string representation.

In addition to the parsed Prefix information returned by kind, PrefixComponent also holds the raw and unparsed OsStr slice, returned by as_os_str.

Instances of this struct can be obtained by matching against the Prefix variant on Component.

Does not occur on Unix.

Examples

use std::path::{Component, Path, Prefix};
use std::ffi::OsStr;

let path = Path::new(r"c:\you\later\");
match path.components().next().unwrap() {
    Component::Prefix(prefix_component) => {
        assert_eq!(Prefix::Disk(b'C'), prefix_component.kind());
        assert_eq!(OsStr::new("c:"), prefix_component.as_os_str());
    }
    _ => unreachable!(),
}

Implementations

impl<'a> PrefixComponent<'a>

pub fn kind(&self) -> Prefix<'a>

Returns the parsed prefix data.

See Prefix’s documentation for more information on the different kinds of prefixes.

pub fn as_os_str(&self) -> &'a OsStr

Returns the raw OsStr slice for this prefix.

Trait Implementations

impl<'a> Clone for PrefixComponent<'a>

fn clone(&self) -> PrefixComponent<'a>

Returns a copy of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for PrefixComponent<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for PrefixComponent<'_>

fn hash<H: Hasher>(&self, h: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,

Feeds a slice of this type into the given Hasher.

impl Ord for PrefixComponent<'_>

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

const fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

const fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

const fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl<'a> PartialEq<PrefixComponent<'a>> for PrefixComponent<'a>

fn eq(&self, other: &PrefixComponent<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

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

impl<'a> PartialOrd<PrefixComponent<'a>> for PrefixComponent<'a>

fn partial_cmp(&self, other: &PrefixComponent<'a>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

const fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

const fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

const fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

const fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
