Enum camino::Utf8Prefix [−][src]
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 camino::{Utf8Component, Utf8Path, Utf8Prefix}; use camino::Utf8Prefix::*; fn get_path_prefix(s: &str) -> Utf8Prefix { let path = Utf8Path::new(s); match path.components().next().unwrap() { Utf8Component::Prefix(prefix_component) => prefix_component.kind(), _ => panic!(), } } assert_eq!(Verbatim("pictures"), get_path_prefix(r"\\?\pictures\kittens")); assert_eq!(VerbatimUNC("server", "share"), get_path_prefix(r"\\?\UNC\server\share")); assert_eq!(VerbatimDisk(b'C'), get_path_prefix(r"\\?\c:\")); assert_eq!(DeviceNS("BrainInterface"), get_path_prefix(r"\\.\BrainInterface")); assert_eq!(UNC("server", "share"), get_path_prefix(r"\\server\share")); assert_eq!(Disk(b'C'), get_path_prefix(r"C:\Users\Rust\Pictures\Ferris"));
Variants
Verbatim(&'a str)
Verbatim prefix, e.g., \\?\cat_pics
.
Verbatim prefixes consist of \\?\
immediately followed by the given
component.
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 str)
Device namespace prefix, e.g., \\.\COM42
.
Device namespace prefixes consist of \\.\
immediately followed by the
device name.
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.
Implementations
impl<'a> Utf8Prefix<'a>
[src]
pub fn is_verbatim(&self) -> bool
[src]
Determines if the prefix is verbatim, i.e., begins with \\?\
.
Examples
use camino::Utf8Prefix::*; assert!(Verbatim("pictures").is_verbatim()); assert!(VerbatimUNC("server", "share").is_verbatim()); assert!(VerbatimDisk(b'C').is_verbatim()); assert!(!DeviceNS("BrainInterface").is_verbatim()); assert!(!UNC("server", "share").is_verbatim()); assert!(!Disk(b'C').is_verbatim());
