Struct WriteBackCallback 

#[repr(C)]
pub struct WriteBackCallback {
    pub cb: WriteBackCallbackType,
    pub ctx: OptionRefAny,
}

Callback that can run when a thread receives a WriteBack message

Fields

cb: WriteBackCallbackType

ctx: OptionRefAny

For FFI: stores the foreign callable (e.g., PyFunction) Native Rust code sets this to None

Implementations

impl WriteBackCallback

pub fn new(cb: WriteBackCallbackType) -> Self

Create a new WriteBackCallback

pub fn invoke( &self, thread_data: RefAny, writeback_data: RefAny, callback_info: CallbackInfo, ) -> Update

Invoke the callback

Trait Implementations

impl Clone for WriteBackCallback

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WriteBackCallback

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

Formats the value using the given formatter.

impl From<extern "C" fn(RefAny, RefAny, CallbackInfo) -> Update> for WriteBackCallback

fn from(cb: WriteBackCallbackType) -> Self

Converts to this type from the input type.

impl Hash for WriteBackCallback

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 Ord for WriteBackCallback

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for WriteBackCallback

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.

impl PartialOrd for WriteBackCallback

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
