Enum FieldProjKind

pub enum FieldProjKind {
    Adt(TypeDeclId, Option<VariantId>),
    Tuple(usize),
    ClosureState,
}

Variants

Adt(TypeDeclId, Option<VariantId>)

Tuple(usize)

If we project from a tuple, the projection kind gives the arity of the tuple.

ClosureState

Access to a field in a closure state. We eliminate this in a micro-pass ([crate::update_closure_signatures]).

Trait Implementations

impl Clone for FieldProjKind

fn clone(&self) -> FieldProjKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FieldProjKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FieldProjKind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Drive for FieldProjKind

fn drive<V: Visitor>(&self, visitor: &mut V)

impl DriveMut for FieldProjKind

fn drive_mut<V: VisitorMut>(&mut self, visitor: &mut V)

impl PartialEq for FieldProjKind

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

impl Serialize for FieldProjKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
