Struct rustc_ast::ast::PathSegment
source · pub struct PathSegment {
pub ident: Ident,
pub id: NodeId,
pub args: Option<P<GenericArgs>>,
}
Expand description
A segment of a path: an identifier, an optional lifetime, and a set of types.
E.g., std
, String
or Box<T>
.
Fields
ident: Ident
The identifier portion of this path segment.
id: NodeId
args: Option<P<GenericArgs>>
Type/lifetime parameters attached to this path. They come in
two flavors: Path<A,B,C>
and Path(A,B) -> C
.
None
means that no parameter list is supplied (Path
),
Some
means that parameter list is supplied (Path<X, Y>
)
but it can be empty (Path<>
).
P
is used as a size optimization for the common case with no parameters.

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.
