vis: Visibility<DefId>

Implementations

impl<'tcx> FieldDef

pub fn ty(&self, tcx: TyCtxt<'tcx>, arg: GenericArgsRef<'tcx>) -> Ty<'tcx>

Returns the type of this field. The resulting type is not normalized. The arg is typically obtained via the second field of TyKind::Adt.

pub fn ident(&self, tcx: TyCtxt<'_>) -> Ident

Computes the Ident of this variant by looking up the Span

pub fn is_unnamed(&self) -> bool

Returns whether the field is unnamed

Trait Implementations

impl Debug for FieldDef

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

Formats the value using the given formatter.

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

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

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

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

impl Hash for FieldDef

fn hash<H: Hasher>(&self, s: &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<'__ctx> HashStable<StableHashingContext<'__ctx>> for FieldDef

fn hash_stable( &self, __hcx: &mut StableHashingContext<'__ctx>, __hasher: &mut StableHasher, )

impl PartialEq for FieldDef

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
