Struct ArgumentStack

pub struct ArgumentStack { /* private fields */ }

Stores the argument context for calls in IR evaluation.

Implementations

impl ArgumentStack

pub const fn new() -> Self

Create a new, empty argument stack.

pub fn get_base(&self) -> usize

Returns the index of the end of the argument stack. Call and save this before adding arguments.

pub fn get_len(&self, base: usize) -> usize

Calculates the number of arguments past the given previously retrieved base pointer.

pub fn push(&mut self, argument: Argument)

Push an argument onto the end of the argument stack.

pub fn leave_frame(&mut self, base: usize)

Clear all of the arguments after the given base index, to prepare for the next frame.

pub fn get_args(&self, base: usize, len: usize) -> &[Argument]

Get arguments for the frame based on the given base and len parameters.

pub fn drain_args( &mut self, base: usize, len: usize, ) -> impl Iterator<Item = Argument> + '_

Move arguments for the frame based on the given base and len parameters.

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

Performs copy-assignment from source.

impl Debug for ArgumentStack

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

impl Default for ArgumentStack

fn default() -> ArgumentStack

Returns the “default value” for a type.
