Trait CallOn

pub trait CallOn<T>: CallInto<T> {
    // Required method
    fn call_on<F>(&self, f: F) -> Self::Output
       where F: FnMut(&T) -> Self::Output;
}

The CallOn trait enables an object to be passed onto a unary, or single value, function that is applied to the object.

Required Methods

fn call_on<F>(&self, f: F) -> Self::Output

where F: FnMut(&T) -> Self::Output,

The call_on method allows an object to be passed onto a function that takes a reference to the object. This is useful for cases where you want to perform an operation on an object without needing to extract it from a container or context.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
