Struct TaggedStack 

#[repr(C)]
pub struct TaggedStack {
    pub base: *mut u64,
    pub sp: usize,
    pub capacity: usize,
}

Stack state for the tagged value stack

Fields

base: *mut u64

Pointer to the base of the stack array

sp: usize

Current stack pointer (index into array, points to next free slot)

capacity: usize

Total capacity of the stack (number of slots)

Implementations

impl TaggedStack

pub fn new(capacity: usize) -> TaggedStack
