Trait IntoFinishOutcome

pub trait IntoFinishOutcome {
    // Required method
    fn into_finish_outcome(self) -> FinishOutcome;
}

Expand description

Return-type bridge for Stepper::on_finish / Wizard::on_finish callbacks, so the same setter accepts a callback that cannot fail and one that can.

callback returns	outcome
`()`	`Finished` (finishing always succeeds)
`bool`	`true` → `Finished`, `false` → `Rejected`
`Result<T, E>`	`Ok` → `Finished`, `Err` → `Rejected`
`FinishOutcome`	itself

Required Methods§

This trait is dyn compatible.

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