Trait Try 

pub trait Try {
    type Output;
    type WithOutput<T>: Try;

    // Required method
    fn from_output(output: Self::Output) -> Self;
}

Equivalent of core::ops::Try that doesn’t require nightly and allows changing the output type using a GAT.

Automatically implemented for Option<T> and Result<T, E>. (Logically depends on core::ops::Try, but doesn’t have an explicit dependency as it’s unstable).

Required Associated Types

type Output

type WithOutput<T>: Try

Required Methods

fn from_output(output: Self::Output) -> Self

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
