Struct PathRef

pub struct PathRef<'a>(/* private fields */);

A borrowed reference to a path.

This type is to Path as &str is to String. It provides a way to work with path strings without requiring ownership. Uses Cow to avoid allocations when no normalization is needed, but can normalize internal multiple slashes when required.

Implementations

impl<'a> PathRef<'a>

pub fn new(s: &'a str) -> Self

Create a new PathRef from a string slice.

Leading and trailing slashes are automatically trimmed. Multiple consecutive internal slashes are collapsed to single slashes.

pub fn has_prefix<'b>(&self, prefix: impl Into<PathRef<'b>>) -> bool

Check if this path has the given prefix, respecting path boundaries.

Unlike String::starts_with, this ensures that “foo” does not match “foobar”. The prefix must either:

• Be exactly equal to this path
• Be followed by a ‘/’ delimiter in the original path
• Be empty (matches everything)

Examples

use moq_lite::Path;

let path = Path::new("foo/bar");
assert!(path.has_prefix("foo"));
assert!(path.has_prefix(&Path::new("foo")));
assert!(path.has_prefix("foo/"));
assert!(!path.has_prefix("fo"));

let path = Path::new("foobar");
assert!(!path.has_prefix("foo"));

pub fn as_str(&self) -> &str

Get the path as a string slice.

pub fn is_empty(&self) -> bool

Check if the path is empty.

pub fn len(&self) -> usize

Get the length of the path in bytes.

pub fn to_owned(&self) -> Path

Convert to an owned Path.

Trait Implementations

impl<'a> AsRef<str> for PathRef<'a>

Converts to this type from the input type.

impl<'a> From<&'a str> for PathRef<'a>

fn from(s: &'a str) -> Self

Converts to this type from the input type.

impl From<PathRef<'_>> for Path

impl<'a> PartialEq for PathRef<'a>

fn eq(&self, other: &PathRef<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
