Enum rustdoc_types::GenericParamDefKind

    Lifetime {

}

Variants

Lifetime

Fields

outlives: Vec<String>

Type

Fields

bounds: Vec<GenericBound>

default: Option<Type>

synthetic: bool

This is normally false, which means that this generic parameter is declared in the Rust source text.

If it is true, this generic parameter has been introduced by the compiler behind the scenes.

Example

Consider

pub fn f(_: impl Trait) {}

The compiler will transform this behind the scenes to

pub fn f<impl Trait: Trait>(_: impl Trait) {}

In this example, the generic parameter named impl Trait (and which is bound by Trait) is synthetic, because it was not originally in the Rust source text.

Const

Fields

type_: Type

default: Option<String>

Trait Implementations

impl Clone for GenericParamDefKind

fn clone(&self) -> GenericParamDefKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GenericParamDefKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GenericParamDefKind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for GenericParamDefKind

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<GenericParamDefKind> for GenericParamDefKind

fn eq(&self, other: &GenericParamDefKind) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for GenericParamDefKind

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

Serialize this value into the given Serde serializer.
