THIR datatypes and definitions. See the rustc dev guide for more info.
If you compare the THIR
hir::ExprKind, you will see it is
a good bit simpler. In fact, a number of the more straight-forward
MIR simplifications are already done in the lowering to THIR. For
example, method calls and overloaded operators are absent: they are
expected to be converted into
A THIR expression.
Represents the association of a field identifier and an expression.
A container for a THIR body.
