#[doc(hidden)]pub trait ClassConstructor<Block> { }Expand description
Implemented by #[miniextendr] for each type with an impl block that
declares its class constructor (#[miniextendr(<system>(constructor))],
or a receiver-less new returning Self). Block is a type private to that
impl block, so two such blocks don’t conflict here; the wrapper writer
refuses them (merge_class_blocks).
An impl block with several methods that could be the constructor and
none declared requires it (require_class_constructor): the type then
compiles only when another of its impl blocks declares the constructor.
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
