Struct Path 

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

Reference path type.

Paths are mostly arbitrary sequences of bytes, with two restrictions:

• The path cannot contain any null bytes.
• Each component of the path must be no longer than 255 bytes.

Implementations

impl<'a> Path<'a>

pub const SEPARATOR: u8 = 47u8

Unix path separator.

pub const ROOT: Path<'static>

Root path, equivalent to /.

pub fn new<P>(p: &'a P) -> Self

where P: AsRef<[u8]> + ?Sized,

Create a new Path.

This panics if the input is invalid, use Path::try_from if error handling is desired.

Panics

Panics if the path contains any null bytes or if a component of the path is longer than 255 bytes.

pub fn is_absolute(self) -> bool

Get whether the path is absolute (starts with /).

pub fn display(self) -> BytesDisplay<'a>

Get an object that implements Display to allow conveniently printing paths that may or may not be valid UTF-8. Non-UTF-8 characters will be replaced with ‘�’.

pub fn join(self, path: impl AsRef<[u8]>) -> PathBuf

Create a new PathBuf joining self with path.

This will add a separator if needed. Note that if the argument is an absolute path, the returned value will be equal to path.

Panics

Panics if the argument is not a valid path.

pub fn components(self) -> Components<'a>

Get an iterator over each Component in the path.

pub fn to_str(self) -> Result<&'a str, Utf8Error>

Convert to a &str if the path is valid UTF-8.

Trait Implementations

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

impl<'a> Clone for Path<'a>

fn clone(&self) -> Path<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Path<'_>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> From<Path<'a>> for &'a Path

Available on crate feature std and Unix only.

fn from(p: Path<'a>) -> &'a Path

Converts to this type from the input type.

impl<'a> From<Path<'a>> for PathBuf

fn from(p: Path<'a>) -> Self

Converts to this type from the input type.

impl<'a> Hash for Path<'a>

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

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<'a> Ord for Path<'a>

fn cmp(&self, other: &Path<'a>) -> 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.

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

where Self: Sized,

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

impl<T> PartialEq<T> for Path<'_>

where T: AsRef<[u8]>,

fn eq(&self, other: &T) -> 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.

fn partial_cmp(&self, other: &Path<'a>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
