Enum PlaceElem

    Downcast(Option<Symbol>, VariantIdx),
    Index(Local),

Variants

Deref

Field(FieldIdx)

Downcast(Option<Symbol>, VariantIdx)

Index(Local)

ConstantIndex

Fields

offset: u64

index or -index (in Python terms), depending on from_end

min_length: u64

The thing being indexed must be at least this long. For arrays this is always the exact length.

from_end: bool

Counting backwards from end? This is always false when indexing an array.

Trait Implementations

impl Clone for PlaceElem

fn clone(&self) -> PlaceElem

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PlaceElem

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

Formats the value using the given formatter.

impl<__D: TyDecoder> Decodable<__D> for PlaceElem

fn decode(__decoder: &mut __D) -> Self

impl<__E: TyEncoder> Encodable<__E> for PlaceElem

fn encode(&self, __encoder: &mut __E)

impl Hash for PlaceElem

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 PlaceElem

fn eq(&self, other: &PlaceElem) -> 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.
