Variants

TrivialEqual

The two statements are trivially equal; same kind

ConsideredEqual(BasicBlock)

The two statements are considered equal, but may be of different kinds. The BasicBlock field is the basic block to jump to when performing the branch-same optimization. For example, _0 = _1 and discriminant(_0) = discriminant(0) are considered equal if 0 is a fieldless variant of an enum. But we don’t want to jump to the basic block with the SetDiscriminant, as that is not legal if _1 is not the 0 variant index

NotEqual

The two statements are not equal

Returns a copy of the value. Read more
Performs copy-assignment from source. Read more
This method tests for self and other values to be equal, and is used by ==. Read more
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason. Read more

Calls U::from(self).

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