Implementations

impl TypeDefSequence

pub fn of<T>() -> Selfwhere T: TypeInfo + 'static,

Use this constructor if you want to instantiate from a given compile-time type.

impl<T> TypeDefSequence<T>where T: Form,

pub fn new(type_param: <T as Form>::Type) -> Self

Creates a new sequence type.

Use this constructor if you want to instantiate from a given meta type.

pub fn type_param(&self) -> &T::Type

Returns the element type of the sequence type.
