fn implied_bounds_program_clauses<'a, I, Wc>(
    builder: &'a mut ClauseBuilder<'_, I>,

    where_clauses: Wc

    I: Interner,

Expand description

Generates the “implied bounds” clauses for an applicative type with the name type_name. For example, if type_name represents a struct S that is declared like:

struct S<T> where T: Eq {  }

then we would generate the rule:

FromEnv(T: Eq) :- FromEnv(S<T>)

§Parameters

builder – the clause builder. We assume all the generic types from S are in scope.
type_name – in our example above, the name S
where_clauses – the list of where clauses declared on the type (T: Eq, in our example).
