Struct CallbackInterfaceDef 

pub struct CallbackInterfaceDef {
    pub name: String,
    pub doc: Option<String>,
    pub deprecated: Option<String>,
    pub methods: Vec<Function>,
}

A callback interface: a set of methods the consumer implements and the producer invokes.

A callback interface is the inverse of an InterfaceDef. A consumer passes an implementation (a class instance, a closure record, a trait object) wherever the type appears as a parameter; the producer keeps it alive as long as it needs to and calls its methods, possibly from any thread. At the C ABI it lowers to a context pointer plus a vtable of function pointers; see the C ABI contract.

Methods are synchronous (never async or cancellable) and return nothing or any type except an iterator or a callback interface; a string, bytes, or buffer return is a run the consumer allocates and the producer adopts. A method may declare throws when an error domain is in scope, letting the consumer report that domain’s codes. Parameters may use any type other than a callback interface or an iterator. A callback interface may itself be passed, bare or optional (Listener?), as a parameter of a function or interface member.

Fields

name: String

Callback interface type name (for example MessageListener).

doc: Option<String>

Human-readable documentation, propagated to the generated bindings. None when undocumented.

deprecated: Option<String>

Deprecation notice for the whole type; when set, generators annotate the emitted type. None means the callback interface is current.

methods: Vec<Function>

Methods the consumer implements, in vtable order. Must be non-empty.
