Struct AnyEvent

pub struct AnyEvent { /* private fields */ }

A dynamic runtime event.

This is a wrapper of Box<dyn Any + Send>, but saves the underlying type name for better Debug impl.

See LspService::emit for usages of this type.

Implementations

impl AnyEvent

pub fn type_name(&self) -> &'static str

Get the underlying type name for debugging purpose.

The result string is only meant for debugging. It is not stable and cannot be trusted.

pub fn is<T: Send + 'static>(&self) -> bool

Returns true if the inner type is the same as T.

pub fn downcast_ref<T: Send + 'static>(&self) -> Option<&T>

Returns some reference to the inner value if it is of type T, or None if it isn’t.

pub fn downcast_mut<T: Send + 'static>(&mut self) -> Option<&mut T>

Returns some mutable reference to the inner value if it is of type T, or None if it isn’t.

pub fn downcast<T: Send + 'static>(self) -> Result<T, Self>

Attempt to downcast it to a concrete type.

Errors

Returns self if the type mismatches.

Trait Implementations

impl Debug for AnyEvent

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
