Trait EndpointOptionExt 

pub trait EndpointOptionExt<T>: Endpoint<Output = Option<T>> + Sized {
    // Provided methods
    fn map_some<F, U>(self, f: F) -> MapSome<Self, F>
       where F: FnOnce(T) -> U + Clone + Send + Sync { ... }
    fn ok_or_else<F, U>(self, f: F) -> OkOrElse<Self, F>
       where F: FnOnce() -> U + Clone + Send + Sync { ... }
}

A set of extension methods which is available when the output is value is an Option.

Provided Methods

fn map_some<F, U>(self, f: F) -> MapSome<Self, F>

where F: FnOnce(T) -> U + Clone + Send + Sync,

Create an endpoint which will map the value to a new type with given function.

fn ok_or_else<F, U>(self, f: F) -> OkOrElse<Self, F>

where F: FnOnce() -> U + Clone + Send + Sync,

Create an endpoint which will transform the returned value into a Result.

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.
