Struct ra_ap_vfs::AbsPathBuf

pub struct AbsPathBuf(/* private fields */);

Wrapper around an absolute Utf8PathBuf.

Implementations

impl AbsPathBuf

pub fn assert(path: Utf8PathBuf) -> AbsPathBuf

Wrap the given absolute path in AbsPathBuf

Panics

Panics if path is not absolute.

pub fn assert_utf8(path: PathBuf) -> AbsPathBuf

Wrap the given absolute path in AbsPathBuf

Panics

Panics if path is not absolute.

pub fn as_path(&self) -> &AbsPath

Coerces to an AbsPath slice.

Equivalent of Utf8PathBuf::as_path for AbsPathBuf.

pub fn pop(&mut self) -> bool

Equivalent of Utf8PathBuf::pop for AbsPathBuf.

Note that this won’t remove the root component, so self will still be absolute.

pub fn push<P>(&mut self, suffix: P)

where P: AsRef<Utf8Path>,

Equivalent of PathBuf::push for AbsPathBuf.

Extends self with path.

If path is absolute, it replaces the current path.

On Windows:

• if path has a root but no prefix (e.g., \windows), it replaces everything except for the prefix (if any) of self.
• if path has a prefix but no root, it replaces self.
• if self has a verbatim prefix (e.g. \\?\C:\windows) and path is not empty, the new path is normalized: all references to . and .. are removed.

Methods from Deref<Target = AbsPath>

pub fn parent(&self) -> Option<&AbsPath>

Equivalent of Utf8Path::parent for AbsPath.

pub fn absolutize(&self, path: impl AsRef<Utf8Path>) -> AbsPathBuf

Equivalent of Utf8Path::join for AbsPath with an additional normalize step afterwards.

pub fn join(&self, path: impl AsRef<Utf8Path>) -> AbsPathBuf

Equivalent of Utf8Path::join for AbsPath.

pub fn normalize(&self) -> AbsPathBuf

Normalize the given path:

• Removes repeated separators: /a//b becomes /a/b
• Removes occurrences of . and resolves ...
• Removes trailing slashes: /a/b/ becomes /a/b.

Example

let abs_path_buf = AbsPathBuf::assert("/a/../../b/.//c//".into());
let normalized = abs_path_buf.normalize();
assert_eq!(normalized, AbsPathBuf::assert("/b/c".into()));

pub fn to_path_buf(&self) -> AbsPathBuf

Equivalent of Utf8Path::to_path_buf for AbsPath.

pub fn canonicalize(&self) -> !

pub fn strip_prefix(&self, base: &AbsPath) -> Option<&RelPath>

Equivalent of Utf8Path::strip_prefix for AbsPath.

Returns a relative path.

pub fn starts_with(&self, base: &AbsPath) -> bool

pub fn ends_with(&self, suffix: &RelPath) -> bool

pub fn name_and_extension(&self) -> Option<(&str, Option<&str>)>

pub fn file_name(&self) -> Option<&str>

pub fn extension(&self) -> Option<&str>

pub fn file_stem(&self) -> Option<&str>

pub fn as_os_str(&self) -> &OsStr

pub fn as_str(&self) -> &str

pub fn display(&self) -> !

👎Deprecated: use Display instead

pub fn exists(&self) -> !

👎Deprecated: use std::fs::metadata().is_ok() instead

pub fn components(&self) -> Utf8Components<'_>

impl Deref for AbsPathBuf

type Target = AbsPath

The resulting type after dereferencing.

fn deref(&self) -> &AbsPath

Formats the value using the given formatter.

impl From<AbsPathBuf> for VfsPath

fn from(v: AbsPathBuf) -> Self

Converts to this type from the input type.

impl Hash for AbsPathBuf

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for AbsPathBuf

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.
