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.

impl Eq for PathSlice

impl StructuralPartialEq for PathSlice

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
