Implementations

impl GenericArgs

pub(crate) fn is_empty(&self) -> bool

pub(crate) fn constraints<'a>( &'a self, ) -> Box<dyn Iterator<Item = AssocItemConstraint> + 'a>

impl GenericArgs

fn print<'a, 'tcx: 'a>( &'a self, cx: &'a Context<'tcx>, ) -> impl Display + 'a + Captures<'tcx>

Trait Implementations

impl Clone for GenericArgs

fn clone(&self) -> GenericArgs

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GenericArgs

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

Formats the value using the given formatter.

impl FromClean<GenericArgs> for GenericArgs

fn from_clean(args: GenericArgs, renderer: &JsonRenderer<'_>) -> Self

impl Hash for GenericArgs

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<'a> IntoIterator for &'a GenericArgs

type IntoIter = Box<dyn Iterator<Item = GenericArg> + 'a>

Which kind of iterator are we turning this into?

type Item = GenericArg

The type of the elements being iterated over.

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for GenericArgs

fn eq(&self, other: &GenericArgs) -> 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 Eq for GenericArgs

impl StructuralPartialEq for GenericArgs

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.
