Enum ProjectionKind 

pub enum ProjectionKind {
    Deref,
    Field {
        field_idx: u32,
        variant_idx: u32,
    },
    Index,
    Subslice,
    UnwrapUnsafeBinder,
}

Variants

Deref

A dereference of a pointer, reference or Box<T> of the given type.

Field

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.

Fields

field_idx: u32

variant_idx: u32

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].

UnwrapUnsafeBinder

unwrap_binder!(expr)

Trait Implementations

impl Clone for ProjectionKind

fn clone(&self) -> ProjectionKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProjectionKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for ProjectionKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ProjectionKind

fn eq(&self, other: &ProjectionKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
