Enum rustc_mir::borrow_check::nll::universal_regions::DefiningTy [−][src]
pub enum DefiningTy<'tcx> { Closure(DefId, ClosureSubsts<'tcx>), Generator(DefId, GeneratorSubsts<'tcx>, GeneratorMovability), FnDef(DefId, &'tcx Substs<'tcx>), Const(DefId, &'tcx Substs<'tcx>), }

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.
Variants
Closure(DefId, ClosureSubsts<'tcx>)

)

The MIR is a closure. The signature is found via
ClosureSubsts::closure_sig_ty
.
Generator(DefId, GeneratorSubsts<'tcx>, GeneratorMovability)
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
The MIR is a generator. The signature is that generators take
no parameters and return the result of
ClosureSubsts::generator_return_ty
.
FnDef(DefId, &'tcx Substs<'tcx>)
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
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.
Const(DefId, &'tcx Substs<'tcx>)
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
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.

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.
