I have a container that contains a generic T.

struct Container<T> {
    content: T,
}

I would like for it to "absorb" into() calls so people can directly create Container<...> instead of having to first call u.into() to get a T and then wrap it in Container<T>.

For example, I would like to do

let s = "Hello World!";
let container: Container<String> = s.into():

instead of having to do

let s = "Hello World!";
let container: Container<String> = Container {
    content: s.into()
}

I wanted to achieve it like this:

impl<T, U> From<U> for Container<T>
where
    T: From<U>,
{
    fn from(value: U) -> Self {
        Self {
            content: value.into(),
        }
    }
}

The compiler gives me an error message that I don't really understand:

conflicting implementations of trait `std::convert::From<Container<_>>` for type `Container<_>`
conflicting implementation in crate `core`:
- impl<T> std::convert::From<T> for T;rustcE0119

Is what I want to do even possible?

Thanks in advance for any pointers
