Struct FnTable 

Source 
pub struct FnTable { /* private fields */ }
Expand description

The per-program native ENTRY TABLE (EXODIA 4.7’s hot-swap seam): two atomic slots per function — [entry pointer, register count] — written when a function’s chain compiles, read by native call stencils through a patched slot address, and the place Tier-2 swaps optimized code in. The backing Vec never reallocates (fixed at construction), so slot addresses are stable for the program’s lifetime.

Implementations§

Source§

impl FnTable

Source

pub fn new(functions: usize) -> Self

Source

pub fn publish(&self, fi: usize, entry: i64, register_count: i64)

Publish a compiled entry (pointer + callee register count).

Source

pub fn slot_addr(&self, fi: usize) -> i64

The address of function fi’s [entry, regcount] slot pair — patched into call stencils as an immediate.

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

where T: Any + Send + Sync,

§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
