Struct std::path::PrefixComponent 1.0.0
[−]
[src]
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!(), }Run
Methods
impl<'a> PrefixComponent<'a>
[src]
pub fn kind(&self) -> Prefix<'a>
[src]

See Prefix
's documentation for more information on the different
kinds of prefixes.
pub fn as_os_str(&self) -> &'a OsStr
[src]
Returns the raw OsStr
slice for this prefix.
