Implementations§

source§

impl TypeDefSequence

source

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

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

source§

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

source

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

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