Struct former::exposed::FormingEndWrapper

pub struct FormingEndWrapper<Storage, Context> { /* private fields */ }

A wrapper around a closure to be used as a FormingEnd.

This struct allows for dynamic dispatch of a closure that matches the FormingEnd trait’s call method signature. It is useful for cases where a closure needs to be stored or passed around as an object implementing FormingEnd.

Type Parameters

• Storage - The type of the container being processed. This type is passed to the closure when it’s called.
• Context - The type of the context that may be altered or returned by the closure. This allows for flexible manipulation of context based on the container.

Implementations

impl<Storage, Context> FormingEndWrapper<Storage, Context>

pub fn new( closure: impl Fn(Storage, Option<Context>) -> Context + 'static ) -> Self

Constructs a new FormingEndWrapper with the provided closure.

Parameters

• closure - A closure that matches the expected signature for transforming a container and context into a new context. This closure is stored and called by the call method of the FormingEnd trait implementation.

Returns

Returns an instance of FormingEndWrapper encapsulating the provided closure.
