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§

impl HasAttrs for Path

source§

const SUPPORTS_CUSTOM_INNER_ATTRS: bool = false

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.
