Member Enumeration Documentation

◆ Mode

enum mim::Checker::Mode

Enumerator

Check

In Mode::Check, type inference is happening and Infers will be resolved, if possible.

Also, two free but different Vars are considered α-equivalent.

Test

In Mode::Test, no type inference is happening and Infers will not be touched.

Also, Two free but different Vars are not considered α-equivalent.

Can value be assigned to sth of type?

Note: This is different from equiv(type, value->type()) since type may be dependent.
