Enum CallFrame 

pub enum CallFrame {
    Lua(Frame),
    Cont(NativeCont),
}

An entry on a thread’s call stack: either a Lua activation record or a continuation frame standing in for a yieldable native (pcall/xpcall).

A Cont sits just below the call it protects. When that call returns, yields-to-completion, or errors, the interpreter consumes the Cont to wrap the outcome — the analogue of PUC lua_pcallk’s continuation k. Keeping it on the same stack as Lua frames means a coroutine.yield crossing it is preserved and restored automatically with the thread’s saved context.

Variants

Lua(Frame)

A Lua activation record.

Tuple Fields

0: Frame

The activation record.

Cont(NativeCont)

A continuation guarding a yieldable native call (pcall / xpcall / metamethod / __close / __pairs).

Tuple Fields

0: NativeCont

The continuation record.

Implementations

impl CallFrame

pub fn lua(&self) -> Option<&Frame>

Borrow the inner Lua frame if this is a Lua variant.

pub fn lua_mut(&mut self) -> Option<&mut Frame>

Mutably borrow the inner Lua frame if this is a Lua variant.

Trait Implementations

impl Clone for CallFrame

fn clone(&self) -> CallFrame

Returns a duplicate of the value.

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

Performs copy-assignment from source.
