Struct std::path::PrefixComponent

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

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!(),
}

Methods

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> Copy for PrefixComponent<'a>

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

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

Formats the value using the given formatter.

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 ==.

#[must_use]

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

This method tests for !=.

impl<'a> Eq for PrefixComponent<'a>

impl<'_> Ord for PrefixComponent<'_>

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

default fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp #44095)

Returns max if self is greater than max, and min if self is less than min. Otherwise this will return self. Panics if min > max.

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.

#[must_use]

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

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

#[must_use]

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

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

#[must_use]

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

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

#[must_use]

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

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

impl<'_> Hash for PrefixComponent<'_>

fn hash<H: Hasher>(&self, h: &mut H)

Feeds this value into the given [Hasher].

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

Feeds a slice of this type into the given [Hasher].

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

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

Returns a copy of the value.

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

Performs copy-assignment from source.
