Struct TempObjFile 

pub struct TempObjFile { /* private fields */ }

A unique path to a temporary file, exposed as an object store path

Unlike TempFile, this does not create an empty file. We create a temporary directory and then construct a path inside it, following the same pattern as TempStdPath. This avoids holding an open file handle, which on Windows would prevent atomic renames to the same path.

Methods from Deref<Target = ObjPath>

pub const ROOT: Path

pub fn parts_count(&self) -> usize

Returns the number of PathParts in this Path

This is equivalent to calling .parts().count() manually.

Performance

This operation is O(n).

pub fn is_root(&self) -> bool

True if this Path points to the root of the store, equivalent to Path::from("/").

See also Path::ROOT.

Example

assert!(Path::from("/").is_root());
assert!(Path::parse("").unwrap().is_root());

pub fn parts(&self) -> PathParts<'_>

Returns the PathParts of this Path

Equivalent to calling .into_iter() on a &Path.

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

Returns a copy of this Path with the last path segment removed

Returns None if this path has zero segments.

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

Returns the last path segment containing the filename stored in this Path

Returns None only if this path is the root path.

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

Returns the extension of the file stored in this Path, if any

pub fn prefix_match( &self, prefix: &Path, ) -> Option<impl Iterator<Item = PathPart<'_>>>

Returns an iterator of the PathPart of this Path after prefix

Returns None if the prefix does not match.

pub fn prefix_matches(&self, prefix: &Path) -> bool

Returns true if this Path starts with prefix

pub fn child<'a>(&self, child: impl Into<PathPart<'a>>) -> Path

👎Deprecated:

use .join() or .clone().join() instead

Creates a new child of this Path

Trait Implementations

impl AsRef<Path> for TempObjFile

fn as_ref(&self) -> &ObjPath

Converts this type into a shared reference of the (usually inferred) input type.

impl Default for TempObjFile

fn default() -> Self

Returns the “default value” for a type.

impl Deref for TempObjFile

type Target = Path

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
