Struct iref::Path

pub struct Path<'a> { /* fields omitted */ }

Implementations

impl<'a> Path<'a>

pub fn len(&self) -> usize

Byte length of the path.

pub fn closed_len(&self) -> usize

The inner data length (in bytes), without the trailing / if the path is open.

pub fn as_bytes(&self) -> &[u8]

Returns a reference to the byte representation of the path.

pub fn into_bytes(self) -> &'a [u8]

Converts this path into the underlying bytes slice.

pub fn as_str(&self) -> &str

Get the underlying path slice as a string slice.

pub fn into_str(self) -> &'a str

Convert this path into the underlying path slice.

pub fn as_pct_str(&self) -> &PctStr

Get the underlying path slice as a percent-encoded string slice.

pub fn as_iri_ref(&self) -> IriRef<'_>

Get the path slice as an IRI reference.

pub fn into_iri_ref(self) -> IriRef<'a>

Convert this path into an IRI reference.

pub fn is_empty(&self) -> bool

Checks if the path is empty.

Returns true if the path is `` or /.

pub fn is_absolute(&self) -> bool

Checks if the path is absolute.

A path is absolute if it starts with a /. A path is necessarily absolute if the IRI it is contained in contains a non-empty authority.

pub fn is_relative(&self) -> bool

Checks if the path is relative.

A path is relative if it does not start with a /. A path cannot be relative if the IRI it is contained in contains a non-empty authority.

pub fn is_open(&self) -> bool

Checks if the path ends with a / but is not equal to /.

pub fn is_closed(&self) -> bool

pub fn closed(self) -> Path<'a>

pub fn first(&self) -> Option<Segment<'a>>

pub fn directory(&self) -> Path<'a>

Return the path directory part.

This correspond to the path without everything after the right most /.

pub fn segments(&self) -> Segments<'a>

Produces an iterator over the segments of the IRI path.

Note that this is an IRI path, not an IRI reference path: no normalization occurs with . and .. segments. This is done by the IRI reference resolution function.

Empty segments are preserved: the path a//b will raise the three segments a, and `b`. The absolute path `/` has no segments, but the path `/a/` has two segments, `a` and.

pub fn normalized_segments(&self) -> NormalizedSegments<'_>

Iterate over the normalized segments of the path.

Remove the special dot segments .. and . from the iteration using the usual path semantics for dot segments. This may be expensive for large paths since it will need to internally normalize the path first.

pub fn into_normalized_segments(self) -> NormalizedSegments<'a>

Consume the path reference and return an iterator over its normalized segments.

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

Returns the name of the final segment of the path, if there is one.

If the path is a normal file, this is the file name. If it’s the path of a directory, this is the directory name.

This does not consider the normalized version of the path, dot segments are preserved.

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

Returns the path without its final component, if there is one.

pub fn suffix(&self, prefix: Path<'_>) -> Option<PathBuf>

Get the suffix part of this path, if any, with regard to the given prefix path.

Returns Some(suffix) if this path is of the form prefix/suffix where prefix is given as parameter. Returns None otherwise.

Both paths are normalized during the process. The result is a normalized suffix path.

Example

use iref::{Path, PathBuf};

let prefix = Path::try_from("/foo/bar").unwrap();
let path = Path::try_from("/foo/bar/baz").unwrap();
let suffix: PathBuf = path.suffix(prefix).unwrap();

assert_eq!(suffix, "baz");
