Struct RareData

Source

pub struct RareData { /* private fields */ }

Expand description

Bag of lazily-initialized subsystem state. Stores erased pointers that high-tier crates (bao_runtime) can downcast to concrete types.

Implementations§

Source §

impl RareData

Source

pub fn new() -> RareData

Source

pub fn set(&mut self, key: &'static str, ptr: *mut c_void)

Store an erased pointer under the given key.

Source

pub fn get(&self, key: &str) -> Option<*mut c_void>

Retrieve an erased pointer by key.

Source

pub fn remove(&mut self, key: &str) -> Option<*mut c_void>

Remove a stored pointer by key.

Source

pub fn hot_map(&self) -> &HotMap

Access the hot map for fast tagged lookup.

Source

pub fn hot_map_mut(&mut self) -> &mut HotMap

Access the hot map mutably.

Blanket Implementations§

Source §

impl<T> Any for T
where T: 'static + ?Sized,

Source §

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

Source §

impl<T> AsCtxPtr for T
where T: ?Sized,

Source §

fn as_ctx_ptr(&self) -> *mut Self
where Self: Sized,

self’s address as *mut Self for deferred-task / scopeguard / ref_guard ctx slots. The closures/trampolines deref it as shared (&*p) — every method they reach is &self post-R-2, so no write provenance is required; the *mut spelling is purely to match the existing DerefOnDrop / HasAutoFlush / RefCount ABI.
