Expand description

The resulting substitution after solving a goal.

Fields

subst: Substitution<I>

The substitution result.

NB: The is_trivial routine relies on the fact that subst is folded first.

constraints: Constraints<I>

List of constraints that are part of the answer.

delayed_subgoals: Vec<InEnvironment<Goal<I>>>

Delayed subgoals, used when the solver answered with an (incomplete) Answer (instead of a CompleteAnswer).

This method tests for !=.

Apply the given folder folder to self; binders is the number of binders that are in scope when beginning the folder. Typically binders starts as 0, but is adjusted when we encounter Binders<T> in the IR or other similar constructs. Read more

Apply the given visitor visitor to self; binders is the number of binders that are in scope when beginning the visitor. Typically binders starts as 0, but is adjusted when we encounter Binders<T> in the IR or other similar constructs. Read more

Cast a value to type U using CastTo.

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

Shifts this term in one level of binders.

Shifts a term valid at outer_binder so that it is valid at the innermost binder. See DebruijnIndex::shifted_in_from for a detailed explanation. Read more

Shifts this term out one level of binders.

The type returned in the event of a conversion error.

Performs the conversion.
