Trait MaybeMap 

pub trait MaybeMap<Base, Out>: Sized {
    // Required method
    fn maybe_map<R: FnOnce(Base) -> Option<Out>>(self, map: R) -> Option<Out>;
}

Required Methods

fn maybe_map<R: FnOnce(Base) -> Option<Out>>(self, map: R) -> Option<Out>

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.
