Expand description

Different kinds of symbols can coexist even if they share the same textual name. Therefore, they each have a separate universe (known as a “namespace”).

Variants

TypeNS

The type namespace includes structs, enums, unions, traits, and mods (and, by extension, crates).

Note that the type namespace includes other items; this is not an exhaustive list.

ValueNS

The value namespace includes fns, consts, statics, and local variables (including function arguments).

MacroNS

The macro namespace includes macro_rules! macros, declarative macros, procedural macros, attribute macros, derive macros, and non-macro attributes like #[inline] and #[rustfmt::skip].

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.
