Trait OptionUtils

pub trait OptionUtils<T> {
    // Required methods
    fn inner_mut<F>(&mut self, f: F)
       where F: FnOnce(&mut T);
    fn map_into<R>(self) -> Option<R>
       where Self: Sized,
             T: Into<R>;
    fn try_map_into<R, E>(self) -> Result<Option<R>, E>
       where Self: Sized,
             T: TryInto<R, Error = E>;
}

A collection of utilities for working with Rust’s Option type.

Required Methods

fn inner_mut<F>(&mut self, f: F)

where F: FnOnce(&mut T),

Run a function on the inner value of an Option.

fn map_into<R>(self) -> Option<R>

where Self: Sized, T: Into<R>,

Map an Option into another type.

fn try_map_into<R, E>(self) -> Result<Option<R>, E>

where Self: Sized, T: TryInto<R, Error = E>,

Map an Option into another type, returning an error if the conversion fails.

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.
