Struct hir_def::path::GenericArgs

pub struct GenericArgs {
    pub args: Box<[GenericArg]>,
    pub has_self_type: bool,
    pub bindings: Box<[AssociatedTypeBinding]>,
    pub desugared_from_fn: bool,
}

Generic arguments to a path segment (e.g. the i32 in Option<i32>). This also includes bindings of associated types, like in Iterator<Item = Foo>.

Fields

args: Box<[GenericArg]>

has_self_type: bool

This specifies whether the args contain a Self type as the first element. This is the case for path segments like <T as Trait>, where T is actually a type parameter for the path Trait specifying the Self type. Otherwise, when we have a path Trait<X, Y>, the Self type is left out.

bindings: Box<[AssociatedTypeBinding]>

Associated type bindings like in Iterator<Item = T>.

desugared_from_fn: bool

Whether these generic args were desugared from Trait(Arg) -> Output parenthesis notation typically used for the Fn traits.

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 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 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.
