Struct TypeParameters 

pub struct TypeParameters<'a> { /* private fields */ }

Represents a collection of type parameters.

Implementations

impl<'a> TypeParameters<'a>

pub fn new(parameters: &'a [TypeParameter]) -> Self

Constructs a new type parameters collection using None as the calculated parameter types.

Panics

Panics if the count of the given type parameters exceeds the maximum allowed.

pub fn get(&self, name: &str) -> Option<(&TypeParameter, Option<Type>)>

Gets a type parameter and its inferred type from the collection.

Returns None if the name is not a type parameter.

This method also marks the type parameter as referenced.

pub fn reset(&self)

Reset any referenced type parameters.

pub fn referenced( &self, ) -> impl Iterator<Item = (&TypeParameter, Option<Type>)> + use<'_>

Gets an iterator of the type parameters that have been referenced since the last reset.

Trait Implementations

impl<'a> Clone for TypeParameters<'a>

fn clone(&self) -> TypeParameters<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for TypeParameters<'a>

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

Formats the value using the given formatter.
