Struct dae_parser::Ref

#[repr(transparent)]
pub struct Ref<A, T: ?Sized> {
    pub val: A,
    // some fields omitted
}

A wrapper around a base type A to indicate that the value is pointing to a value of type T.

This is not a strict type safety barrier; it is possible to convert a Ref to and from its raw version. However this can help in API documentation, as well as to assist type inference in functions like LocalMap::get.

Fields

val: A

The underlying storage or “raw” value.

Implementations

impl<A, T: ?Sized> Ref<A, T>

pub fn new(val: A) -> Self
