Expand description

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

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.

Tuple Fields of User

0: ClearCrossCrate<BindingForm<'tcx>>
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

Returns a copy of the value. Read more

Performs copy-assignment from source. Read more

Formats the value using the given formatter. Read more

Returns true if self has any late-bound regions that are either bound by binder or bound by some binder outside of binder. If binder is ty::INNERMOST, this indicates whether there are any late-bound regions that appear free. Read more

Returns true if this self has any regions that escape binder (and hence are not bound by it). Read more

“Free” regions in this context means that it has any region that is not (a) erased or (b) late-bound. Read more

True if there are any un-erased free regions.

Indicates whether this value references only ‘global’ generic parameters that are the same regardless of what fn we are in. This is used for caching. Read more

True if there are any late-bound regions

Indicates whether this value still has parameters/placeholders/inference variables which could be replaced later, in a way that would change the results of impl specialization. Read more

Layout

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
