Type Alias rings_node::prelude::message::CallbackFn

pub type CallbackFn = Box<dyn MessageCallback + Sync + Send, Global>;

Boxed Callback, for non-wasm, it should be Sized, Send and Sync.

Aliased Type

struct CallbackFn(/* private fields */);

Trait Implementations

impl<T, A> Deref for Box<T, A>where A: Allocator, T: ?Sized,

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T> Error for Box<T, Global>where T: Error,

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.
