Struct rustc_ast::ast::Path

source ·
pub struct Path {
    pub span: Span,
    pub segments: ThinVec<PathSegment>,
    pub tokens: Option<LazyAttrTokenStream>,
}
Expand description

A “Path” is essentially Rust’s notion of a name.

It’s represented as a sequence of identifiers, along with a bunch of supporting information.

E.g., std::cmp::PartialEq.

Fields§

§span: Span§segments: ThinVec<PathSegment>

The segments in the path: the things separated by ::. Global paths begin with kw::PathRoot.

§tokens: Option<LazyAttrTokenStream>

Implementations§

source§

impl Path

source

pub fn from_ident(ident: Ident) -> Path

Convert a span and an identifier to the corresponding one-segment path.

source

pub fn is_global(&self) -> bool

source

pub fn is_potential_trivial_const_arg(&self) -> bool

If this path is a single identifier with no arguments, does not ensure that the path resolves to a const param, the caller should check this.

source§

impl HasAttrs for Path

source§

const SUPPORTS_CUSTOM_INNER_ATTRS: bool = false

This is true if this HasAttrs might support ‘custom’ (proc-macro) inner attributes. Attributes like #![cfg] and #![cfg_attr] are not considered ‘custom’ attributes. Read more
source§

fn attrs(&self) -> &[Attribute]

source§

fn visit_attrs(&mut self, _f: impl FnOnce(&mut AttrVec))

source§

impl HasSpan for Path

source§

fn span(&self) -> Span

impl<CTX: HashStableContext> HashStable<CTX> for Path

source§

fn hash_stable(&self, hcx: &mut CTX, hasher: &mut StableHasher)

source§

impl PartialEq<Symbol> for Path

source§

fn eq(&self, symbol: &Symbol) -> bool

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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.
