Enum rustc_middle::hir::place::ProjectionKind [−][src]
pub enum ProjectionKind { Deref, Field(u32, VariantIdx), Index, Subslice, }
Variants
A dereference of a pointer, reference or Box<T>
of the given type.
Field(u32, VariantIdx)
B.F
where B
is the base expression and F
is
the field. The field is identified by which variant
it appears in along with a field index. The variant
is used for enums.
Some index like B[x]
, where B
is the base
expression. We don’t preserve the index x
because
we won’t need it.
A subslice covering a range of values like B[x..y]
.
