Struct ActionTag 

pub struct ActionTag(/* private fields */);

Tag identifying an action-server callback registered on a Node.

See SubscriptionTag for the usage pattern.

Implementations

impl ActionTag

pub const fn placeholder() -> Self

Sentinel used by macro-emitted init() bodies before the real tag is resolved.

pub const fn new(id: &'static str) -> Self

Construct a tag with an explicit stable identifier.

pub const fn as_str(&self) -> &'static str

Borrow the underlying identifier string.

Trait Implementations

impl Clone for ActionTag

fn clone(&self) -> ActionTag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ActionTag

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

Formats the value using the given formatter.

impl From<ActionTag> for CallbackId<'static>

fn from(tag: ActionTag) -> Self

Converts to this type from the input type.

impl Hash for ActionTag

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<Callback<'_>> for ActionTag

fn eq(&self, other: &Callback<'_>) -> 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.

impl PartialEq<CallbackId<'_>> for ActionTag

fn eq(&self, other: &CallbackId<'_>) -> 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.

impl PartialEq for ActionTag

fn eq(&self, other: &ActionTag) -> 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.
