Trait OptionExt 

pub trait OptionExt<T> {
    // Required method
    fn try_map<R, E, F: FnMut(T) -> Result<R, E>>(
        self,
        f: F,
    ) -> Result<Option<R>, E>;
}

Required Methods

fn try_map<R, E, F: FnMut(T) -> Result<R, E>>( self, f: F, ) -> Result<Option<R>, E>

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.
