Trait TryAllHack 

pub trait TryAllHack {
    type Iter;
    type AllOrFirst;

    // Required method
    fn try_all(iter: Self::Iter) -> Self::AllOrFirst;
}

A hack trait to bypass limitations of type checker.

We have to hack until rust-lang/rust#20400 is closed. CC: paholg.

Required Associated Types

type Iter

type AllOrFirst

Required Methods

fn try_all(iter: Self::Iter) -> Self::AllOrFirst

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.
