Struct ConstructorSpecBuilder

Source 
pub struct ConstructorSpecBuilder<F: Form, Selector, IsPayable, Returns> { /* private fields */ }
Expand description

A builder for constructors.

§Developer Note

Some fields are guarded by a type-state pattern to fail at compile-time instead of at run-time. This is useful to better debug code-gen macros.
