Enum TypeParameter 

pub enum TypeParameter {
    Concrete(String),
    Parametric(Box<ParametricType>),
}

A type parameter that can be either a concrete type or another parametric type.

Variants

Concrete(String)

A concrete type name (e.g., “Person”, “Int”)

Parametric(Box<ParametricType>)

A nested parametric type (e.g., List<Option<Person>>)

Implementations

impl TypeParameter

pub fn concrete(name: impl Into<String>) -> Self

Creates a concrete type parameter.

pub fn parametric(ptype: ParametricType) -> Self

Creates a parametric type parameter.

pub fn as_concrete(&self) -> Option<&str>

Returns the name if this is a concrete type parameter.

pub fn as_parametric(&self) -> Option<&ParametricType>

Returns the parametric type if this is a parametric type parameter.

Trait Implementations

impl Clone for TypeParameter

fn clone(&self) -> TypeParameter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TypeParameter

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TypeParameter

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for TypeParameter

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

Formats the value using the given formatter.

impl Hash for TypeParameter

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 TypeParameter

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

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 TypeParameter
