Struct RegisterComponentFn 

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

Callback struct for registering individual components at startup.

In C: pass a bare extern "C" fn() -> ComponentDef function pointer — it converts automatically via From<RegisterComponentFnType>.

In Python: construct this struct with cb set to a trampoline and ctx set to Some(RefAny(...)) wrapping the Python callable.

Fields

cb: RegisterComponentFnType

ctx: OptionRefAny

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

Trait Implementations

impl Clone for RegisterComponentFn

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 RegisterComponentFn

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

Formats the value using the given formatter.

impl Display for RegisterComponentFn

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

Formats the value using the given formatter.

impl From<extern "C" fn() -> ComponentDef> for RegisterComponentFn

Allow creating callback from a raw function pointer Sets callable to None (for native Rust/C usage)

fn from(cb: RegisterComponentFnType) -> Self

Converts to this type from the input type.

impl Hash for RegisterComponentFn

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

where H: Hasher,

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 RegisterComponentFn

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 RegisterComponentFn

fn eq(&self, rhs: &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 RegisterComponentFn

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.
