Struct Fallback 

pub struct Fallback<T, U> {
    pub first: T,
    pub second: U,
}

A wrapper that tries the first operation, and if it fails, tries the second.

Fields

first: T

second: U

Implementations

impl<T, U> Fallback<T, U>

pub const fn new(first: T, second: U) -> Self

Creates a new Fallback.
