Struct rune::runtime::CallFrame

#[non_exhaustive]
pub struct CallFrame {
    pub ip: usize,
    pub stack_bottom: usize,
    pub isolated: bool,
}

A call frame.

This is used to store the return point after an instruction has been run.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

ip: usize

The stored instruction pointer.

stack_bottom: usize

The top of the stack at the time of the call to ensure stack isolation across function calls.

I.e. a function should not be able to manipulate the size of any other stack than its own.

isolated: bool

Indicates that the call frame is isolated and should force an exit into the vm execution context.

Trait Implementations

impl Clone for CallFrame

fn clone(&self) -> CallFrame

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CallFrame

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

Formats the value using the given formatter.

impl TryClone for CallFrame

fn try_clone(&self) -> Result<Self>

Try to clone the current value, raising an allocation error if it’s unsuccessful.

fn try_clone_from(&mut self, source: &Self) -> Result<(), Error>

Performs copy-assignment from source.
