Struct ExplicitClosure 

Source 
pub struct ExplicitClosure<T, R>(/* private fields */);
Expand description

A tiny, FnOnce-compatible wrapper used to initialize a LazyLock with a captured value.

This is a utility to build LazyLock<T> where the initializer needs to own some value prepared in a const context.

This is required since we need an explicit concrete type for the initializataion function given to LazyLock::new.

You usually don’t need this directly unless you’re calling InterningTable::new_with_values.
