Enum PathSegment

#[non_exhaustive]
pub enum PathSegment {
    SelfType(SelfType),
    SelfValue(SelfValue),
    Ident(Ident),
    Crate(Crate),
    Super(Super),
    Generics(AngleBracketed<PathSegmentExpr, Comma>),
}

Part of a :: separated path.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SelfType(SelfType)

A path segment that contains Self.

SelfValue(SelfValue)

A path segment that contains self.

Ident(Ident)

A path segment that is an identifier.

Crate(Crate)

The crate keyword used as a path segment.

Super(Super)

The super keyword use as a path segment.

Generics(AngleBracketed<PathSegmentExpr, Comma>)

A path segment that is a generic argument.

Trait Implementations

impl Debug for PathSegment

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

Formats the value using the given formatter.

impl OptionSpanned for PathSegment

fn option_span(&self) -> Option<Span>

Get the optional span of the type.

impl Parse for PathSegment

fn parse(p: &mut Parser<'_>) -> Result<Self, Error>

Parse the current item from the parser.

impl PartialEq for PathSegment

fn eq(&self, other: &PathSegment) -> 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 Peek for PathSegment

fn peek(p: &mut Peeker<'_>) -> bool

Peek the parser for the given token.

impl Spanned for PathSegment

fn span(&self) -> Span

Get the span of the type.

impl ToTokens for PathSegment

fn to_tokens( &self, context: &mut MacroContext<'_, '_, '_>, stream: &mut TokenStream, ) -> Result<()>

Turn the current item into tokens.

impl TryClone for PathSegment

fn try_clone(&self) -> Result<Self>

Try to clone the current value, raising an allocation error if it’s unsuccessful.

fn try_clone_from(&mut self, source: &Self) -> Result<(), Error>

Performs copy-assignment from source.

impl Eq for PathSegment

impl StructuralPartialEq for PathSegment
