Deref

Field(FieldIndex)

A field (e.g., f in _1.f).

Index(Idx<Local>)

Index into a slice/array.

ConstantIndex

These indices are generated by slice patterns.

Fields

offset: u64

from_end: bool

Subslice

These indices are generated by slice patterns.

Fields

from: u64

to: u64

Downcast(VariantId)

“Downcast” to a variant of an enum or a coroutine.
