Struct chalk_ir::GenericArg [−][src]
pub struct GenericArg<I: Interner> { /* fields omitted */ }
Expand description
A generic argument, see GenericArgData
for more information.
Implementations
Constructs a generic argument using GenericArgData
.
Gets the interned value.
Gets the underlying data.
Asserts that this is a type argument.
Asserts that this is a lifetime argument.
Asserts that this is a constant argument.
Returns the lifetime if it is one, None
otherwise.

type Result = GenericArg<I>
type Result = GenericArg<I>
The type of value that will be produced once folding is done.
Typically this is Self
, unless Self
contains borrowed
values, in which case owned values are produced (for example,
one can fold over a &T
value where T: Fold
, in which case
you get back a T
, not a &T
). Read more
Apply the given folder folder
to self
; binders
is the
number of binders that are in scope when beginning the
folder. Typically binders
starts as 0, but is adjusted when
we encounter Binders<T>
in the IR or other similar
constructs. Read more

Shifts this term in one level of binders.
Shifts a term valid at outer_binder
so that it is
valid at the innermost binder. See DebruijnIndex::shifted_in_from
