Trait OptionExt 

pub trait OptionExt<T> {
    // Required method
    fn and_then_ok<U, E, F>(self, f: F) -> StdResult<Option<U>, E>
       where F: FnOnce(T) -> StdResult<Option<U>, E>;
}

Required Methods

fn and_then_ok<U, E, F>(self, f: F) -> StdResult<Option<U>, E>

where F: FnOnce(T) -> StdResult<Option<U>, 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.
