Struct Callback 

pub struct Callback<'a> { /* private fields */ }

Runtime callback event delivered to an executable Node.

The value carries the source callback name declared by the component, but does not expose the generated/internal callback ID type to product code.

Implementations

impl<'a> Callback<'a>

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

Borrow the source callback name.

pub fn is_named(self, name: &str) -> bool

Return true when this callback matches name.

Trait Implementations

impl<'a> Clone for Callback<'a>

fn clone(&self) -> Callback<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Callback<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for Callback<'a>

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<Callback<'_>> for ServiceTag

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<Callback<'_>> for SubscriptionTag

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<'a> PartialEq for Callback<'a>

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