Struct AstPath 

pub struct AstPath<'ast>(/* private fields */);

A boxed PathSlice.

Implementations

impl<'ast> AstPath<'ast>

pub fn new_in(arena: &'ast Bump, segments: &[Ident]) -> Self

Creates a new path from a slice of segments by allocating them on the given arena.

pub fn as_slice(&self) -> &PathSlice

Returns the path as a slice.

pub fn as_mut_slice(&mut self) -> &mut PathSlice

Returns the path as a mutable slice.

Methods from Deref<Target = PathSlice>

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<'ast> Debug for AstPath<'ast>

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

Formats the value using the given formatter.

impl Deref for AstPath<'_>

type Target = PathSlice

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for AstPath<'_>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl Hash for AstPath<'_>

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 Ord for AstPath<'_>

fn cmp(&self, other: &Self) -> 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,

Compares and returns the minimum of two values.

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

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for AstPath<'_>

fn eq(&self, other: &Self) -> 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 AstPath<'_>

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

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.
