Enum rustc_middle::hir::place::ProjectionKind

pub enum ProjectionKind {
    Deref,
    Field(u32, VariantIdx),
    Index,
    Subslice,
}

Variants

Deref

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.

Index

Some index like B[x], where B is the base expression. We don't preserve the index x because we won't need it.

Subslice

A subslice covering a range of values like B[x..y].
