The "defining type" for this MIR. The key feature of the "defining type" is that it contains the information needed to derive all the universal regions that are in scope as well as the types of the inputs/output from the MIR. In general, early-bound universal regions appear free in the defining type and late-bound regions appear bound in the signature.

The MIR is a closure. The signature is found via ClosureSubsts::closure_sig_ty.

The MIR is a generator. The signature is that generators take no parameters and return the result of ClosureSubsts::generator_return_ty.

The MIR is a fn item with the given def-id and substs. The signature of the function can be bound then with the fn_sig query.

The MIR represents some form of constant. The signature then is that it has no inputs and a single return value, which is the value of the constant.

Methods

[src]

🔬 This is a nightly-only experimental API. (rustc_private)

Returns a list of all the upvar types for this MIR. If this is not a closure or generator, there are no upvars, and hence it will be an empty list. The order of types in this list will match up with the upvar_decls field of Mir.

Number of implicit inputs -- notably the "environment" parameter for closures -- that appear in MIR but not in the user's code.
