Trait ra_ap_rustc_data_structures::obligation_forest::OutcomeTrait

pub trait OutcomeTrait {
    type Error;
    type Obligation;

    // Required methods
    fn new() -> Self;
    fn record_completed(&mut self, outcome: &Self::Obligation);
    fn record_error(&mut self, error: Self::Error);
}

This trait allows us to have two different Outcome types:

• the normal one that does as little as possible
• one for tests that does some additional work and checking

Required Associated Types

type Error

type Obligation

Required Methods

fn new() -> Self

fn record_completed(&mut self, outcome: &Self::Obligation)

fn record_error(&mut self, error: Self::Error)

Object Safety

This trait is not object safe.

Implementors

impl<O, E> OutcomeTrait for Outcome<O, E>

type Error = Error<O, E>

type Obligation = O
