Enum rustc_middle::mir::LocalInfo[][src]

pub enum LocalInfo<'tcx> {
    User(ClearCrossCrate<BindingForm<'tcx>>),
    StaticRef {
        def_id: DefId,
        is_thread_local: bool,
    },
    ConstRef {
        def_id: DefId,
    },
}

Extra information about a some locals that’s used for diagnostics and for classifying variables into local variables, statics, etc, which is needed e.g. for unsafety checking.

Not used for non-StaticRef temporaries, the return place, or anonymous function parameters.

Variants

User(ClearCrossCrate<BindingForm<'tcx>>)

A user-defined local variable or function parameter

The BindingForm is solely used for local diagnostics when generating warnings/errors when compiling the current crate, and therefore it need not be visible across crates.

StaticRef

A temporary created that references the static with the given DefId.

Fields of StaticRef

def_id: DefIdis_thread_local: bool
ConstRef

A temporary created that references the const with the given DefId

Fields of ConstRef

def_id: DefId
