Struct subxt_codegen::TypeDefParameters

pub struct TypeDefParameters { /* private fields */ }

Represents the set of generic type parameters for generating a type definition e.g. the T in Foo<T>.

Additionally this allows generating a PhantomData type for any type params which are unused in the type definition itself.

Implementations

impl TypeDefParameters

pub fn new(params: Vec<TypeParameter>) -> Self

Create a new TypeDefParameters instance.

pub fn update_unused<'a>( &mut self, fields: impl Iterator<Item = &'a CompositeDefFieldType> )

Update the set of unused type parameters by removing those that are used in the given fields.

pub fn unused_params_phantom_data(&self) -> Option<TypePath>

Construct a core::marker::PhantomData for the type unused type params.

pub fn params(&self) -> &[TypeParameter]

Returns the set of type parameters.

pub fn has_unused_type_params(&self) -> bool

Returns true if there are any unused type params
