/**
 * Marks a method that initializes {@code @NonNull} fields which are not set in the constructor.
 *
 * <p>NullAway treats fields assigned in an initializer method as initialized. This is used for ASM
 * visitor callbacks (such as {@code ClassVisitor.visit(...)}) that the framework guarantees to call
 * before the populated fields are read — something NullAway cannot infer from the constructor alone.
 *
 * <p>NullAway recognizes any annotation whose simple name is {@code Initializer}; see the
 * <a href="https://github.com/uber/NullAway/wiki/Supported-Annotations#initialization">NullAway documentation</a>.
