Self-Reference

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.

Initializing Reference Object

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(); ```

Reset Mechanism

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> = SelfReference::new("self-reference".tostring(), || ""); pinmut!(reference);

// You can reset object to set referencial object to hold object itself. reference.resetunpin(|s| &s[..4]); println!("{}", reference.getref()); // prints "self" ```
