Struct PathSlice

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

A qualified identifier: foo.bar.baz.

This is a list of identifiers, and is never empty.

Implementations

impl PathSlice

pub fn from_ref(segment: &Ident) -> &Self

Creates a new path from a single ident.

pub fn from_mut(segment: &mut Ident) -> &mut Self

Creates a new path from a single ident.

pub fn from_slice(segments: &[Ident]) -> &Self

Creates a new path from a slice of segments.

Panics

Panics if segments is empty.

pub unsafe fn from_slice_unchecked(segments: &[Ident]) -> &Self

Creates a new path from a slice of segments.

Safety

The caller must ensure that segments is not empty.

pub fn from_mut_slice(segments: &mut [Ident]) -> &mut Self

Creates a new path from a mutable slice of segments.

Panics

Panics if segments is empty.

pub unsafe fn from_mut_slice_unchecked(segments: &mut [Ident]) -> &mut Self

Creates a new path from a mutable slice of segments.

Safety

The caller must ensure that segments is not empty.

pub fn span(&self) -> Span

Returns the path’s span.

pub fn segments(&self) -> &[Ident]

Returns the path’s segments.

pub fn segments_mut(&mut self) -> &mut [Ident]

Returns the path’s segments.

pub fn get_ident(&self) -> Option<&Ident>

If this path consists of a single ident, returns the ident.

pub fn get_ident_mut(&mut self) -> Option<&mut Ident>

If this path consists of a single ident, returns the ident.

pub fn first(&self) -> &Ident

Returns the first segment of the path.

pub fn first_mut(&mut self) -> &mut Ident

Returns the first segment of the path.

pub fn last(&self) -> &Ident

Returns the last segment of the path.

pub fn last_mut(&mut self) -> &mut Ident

Returns the last segment of the path.

Trait Implementations

impl Borrow<PathSlice> for Path

fn borrow(&self) -> &PathSlice

Immutably borrows from an owned value.

impl Debug for PathSlice

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

Formats the value using the given formatter.

impl Display for PathSlice

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

Formats the value using the given formatter.

impl Hash for PathSlice

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

Feeds this value into the given Hasher.

impl Ord for PathSlice

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

This method returns an Ordering between self and other.

impl PartialEq<Ident> for PathSlice

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

impl PartialEq<Symbol> for PathSlice

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

impl PartialEq for PathSlice

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

impl PartialOrd for PathSlice

fn partial_cmp(&self, other: &PathSlice) -> 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.

impl ToOwned for PathSlice

type Owned = Path

The resulting type after obtaining ownership.

fn to_owned(&self) -> Self::Owned

Creates owned data from borrowed data, usually by cloning.

fn clone_into(&self, target: &mut Self::Owned)

Uses borrowed data to replace owned data, usually by cloning.
