Struct rustc_middle::ty::abstract_const::AbstractConst
source · Expand description
A tree representing an anonymous constant.
This is only able to represent a subset of MIR
,
and should not leak any information about desugarings.

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.
