Struct CommandParam 

#[non_exhaustive]
pub struct CommandParam(pub Arc<dyn Any + Send + Sync>);

Represents a reference counted dyn Any object parameter for a command request.

Tuple Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

0: Arc<dyn Any + Send + Sync>

Implementations

impl CommandParam

pub fn new(param: impl Any + Send + Sync + 'static) -> Self

New param.

If param is already a CommandParam or Arc<dyn Any + Send + Sync> returns a clone.

pub fn type_id(&self) -> TypeId

Gets the TypeId of the parameter.

pub fn downcast_ref<T: Any>(&self) -> Option<&T>

Gets a typed reference to the parameter if it is of type T.

pub fn is<T: Any>(&self) -> bool

Returns true if the parameter type is T.

Trait Implementations

impl Clone for CommandParam

fn clone(&self) -> CommandParam

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CommandParam

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

Formats the value using the given formatter.

impl IntoVar<Option<CommandParam>> for CommandParam

fn into_var(self) -> Var<Option<CommandParam>>

impl PartialEq for CommandParam

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
