1.0.0[−][src]Enum std::path::Prefix
Windows path prefixes, e.g., C:
or \server\share
.
Windows uses a variety of path prefix styles, including references to drive
volumes (like C:
), network shared folders (like \server\share
), and
others. In addition, some path prefixes are "verbatim" (i.e., prefixed with
\?\
), in which case /
is not treated as a separator and essentially
no normalization is performed.
Examples
use std::path::{Component, Path, Prefix}; use std::path::Prefix::*; use std::ffi::OsStr; fn get_path_prefix(s: &str) -> Prefix { let path = Path::new(s); match path.components().next().unwrap() { Component::Prefix(prefix_component) => prefix_component.kind(), _ => panic!(), } } assert_eq!(Verbatim(OsStr::new("pictures")), get_path_prefix(r"\\?\pictures\kittens")); assert_eq!(VerbatimUNC(OsStr::new("server"), OsStr::new("share")), get_path_prefix(r"\\?\UNC\server\share")); assert_eq!(VerbatimDisk(b'C'), get_path_prefix(r"\\?\c:\")); assert_eq!(DeviceNS(OsStr::new("BrainInterface")), get_path_prefix(r"\\.\BrainInterface")); assert_eq!(UNC(OsStr::new("server"), OsStr::new("share")), get_path_prefix(r"\\server\share")); assert_eq!(Disk(b'C'), get_path_prefix(r"C:\Users\Rust\Pictures\Ferris"));Run
Variants
Verbatim(&'a OsStr)
Verbatim prefix, e.g., \?\cat_pics
.
Verbatim prefixes consist of \?\
immediately followed by the given
component.
VerbatimUNC(&'a OsStr, &'a OsStr)
Verbatim prefix using Windows' Uniform Naming Convention,
e.g., \?\UNC\server\share
.
Verbatim UNC prefixes consist of \?\UNC\
immediately followed by the
server's hostname and a share name.
VerbatimDisk(u8)
Verbatim disk prefix, e.g., \?\C:\
.
Verbatim disk prefixes consist of \?\
immediately followed by the
drive letter and :\
.
DeviceNS(&'a OsStr)
Device namespace prefix, e.g., \.\COM42
.
Device namespace prefixes consist of \.\
immediately followed by the
device name.
UNC(&'a OsStr, &'a OsStr)
Prefix using Windows' Uniform Naming Convention, e.g.
\server\share
.
UNC prefixes consist of the server's hostname and a share name.
Disk(u8)
Prefix C:
for the given disk drive.
Methods
impl<'a> Prefix<'a>
[src]
pub fn is_verbatim(&self) -> bool
[src]
Determines if the prefix is verbatim, i.e., begins with \?\
.
Examples
