Trait OptionUtils

pub trait OptionUtils<T> {
    // Required methods
    fn or_default_with(self, fallback: T) -> T;
    fn if_some<F: FnOnce(&T)>(self, f: F) -> Option<T>;
}

Extension methods for Option<T>.

Required Methods

fn or_default_with(self, fallback: T) -> T

Returns the value inside Some, or the fallback if None.

fn if_some<F: FnOnce(&T)>(self, f: F) -> Option<T>

Executes a closure if the Option is Some.

Returns the same Option back.

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.
