Enum GenericArgument 

pub enum GenericArgument {
    TypeParameter(Type),
    Lifetime(GenericLifetimeParameter),
    Const(ConstGenericArgument),
}

A single generic argument supplied to a generic type or function.

Variants

TypeParameter(Type)

A generic type parameter, e.g. u32 in Vec<u32> or T in HashSet<T>.

Lifetime(GenericLifetimeParameter)

A lifetime parameter, e.g. 'a in Cow<'a, str>.

Const(ConstGenericArgument)

A const generic argument with a concrete evaluated value, e.g. 8 in Size<8>.

Implementations

impl GenericArgument

pub fn render_type_into( &self, id2name: &BiHashMap<PackageId, String>, buffer: &mut String, )

Render this generic argument preserving named lifetimes as-is.

pub fn render_with_inferred_lifetimes_into( &self, id2name: &BiHashMap<PackageId, String>, buffer: &mut String, )

Render this generic argument, replacing named lifetimes with '_.

pub fn display_for_error_into<W: Write>(&self, buffer: &mut W)

Render this generic argument for error messages.

Trait Implementations

impl Clone for GenericArgument

fn clone(&self) -> GenericArgument

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GenericArgument

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GenericArgument

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for GenericArgument

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

Formats the value using the given formatter.

impl Hash for GenericArgument

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 GenericArgument

fn eq(&self, other: &GenericArgument) -> 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 GenericArgument

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for GenericArgument
