Expand description
A constant (expression) that’s not an item or associated item,
but needs its own DefId
for type-checking, const-eval, etc.
These are usually found nested inside types (e.g., array lengths)
or expressions (e.g., repeat counts), and also used to define
explicit discriminant values for enum variants.
You can check if this anon const is a default in a const param
const N: usize = { ... }
with tcx.hir().opt_const_param_default_param_hir_id(..)
Fields
hir_id: HirId
body: BodyId

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.
