Trait IntoMaybeUndefined 

pub trait IntoMaybeUndefined<T> {
    // Required method
    fn into_maybe_undefined(self) -> MaybeUndefined<T>;
}

Utility trait for builder methods for optional values. This allows the caller to either pass in the value itself without wrapping it in Some, or to just pass in an Option if that is what they have, or set it back to undefined.

Required Methods

fn into_maybe_undefined(self) -> MaybeUndefined<T>

Converts this value into a three-state builder argument.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
