A Self-Refernece Helper (Inspired From Selfie)
this crate provides safe access to its self-reference.
the main idea is not initializing references when object not pinned(which is not safe and makes many self-referenial crate more complex)
providing only pinned reference makes lot more easier to design self-referential object.
on self-reference
crate. you only can initialize reference object that has 'static
lifetime means always safe.
The major difference from other self-referential crate is initializing referential object.
you only can initialize reference object that has 'static
lifetime
``rust
let mut reference: SelfReference<String, Ref<str>> = SelfReference::new(String::new(), || {
// you can't get reference of object while initialization.
// only possible cases are reference that has
'static` lifetime.
""
});
pin_mut!(reference);
// this is totally SAFE. this lowers 'static
lifetime into some other lifetime.
reference.get_ref();
```
The only way to initialize reference object is using reset
method. remember!! you can use reset method when SelfReference
object is pinned.
```rust
let mut reference: SelfReference
// You can reset object to set referencial object to hold object itself. reference.resetunpin(|s| &s[..4]); println!("{}", reference.getref()); // prints "self" ```
