Path in rustc_ast::ast - Rust (original) (raw)
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.
The segments in the path: the things separated by ::. Global paths begin with kw::PathRoot.
Convert a span and an identifier to the corresponding one-segment path.
Check if this path is potentially a trivial const arg, i.e., one that can _potentially_be represented without an anon const in the HIR.
If allow_mgca_arg is true (as should be the case in most situations when#![feature(min_generic_const_args)] is enabled), then this always returns true because all paths are valid.
Otherwise, it returns true iff the path has exactly one segment, and it has no generic args (i.e., it is potentially a const parameter).
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

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