Struct Scope 

pub struct Scope { /* private fields */ }

A caching scope handle.

Caching is disabled by default. DialCache::enable opens the outermost enabled scope and hands its Scope to the callback; pass it to every cached call made on behalf of that request. Nested DialCache::enable_in and DialCache::disable_in derive child scopes that share the outer request memo. When the outermost callback completes its scope closes: retained clones no longer enable caching and late work cannot publish into the request memo.

Scope::outside is the pass-through scope of code that runs on behalf of no request: calls made with it invoke their source directly.

Implementations

impl Scope

pub fn outside() -> Scope

The scope of work that runs on behalf of no request. Calls pass straight through to their source.

pub fn is_enabled(&self) -> bool

Whether caching is enabled for calls made with this scope: it was derived from an enabled scope and its outermost scope is still open.
