Struct MutableStackEnvironment 

pub struct MutableStackEnvironment<'a> {
    pub backing: StackEnvironment<'a>,
    pub updates: Vec<(&'a str, usize)>,
}

A mutable stack environment, backed by a static stack environment.

Fields

backing: StackEnvironment<'a>

The backing stack environment that contains the original bindings.

updates: Vec<(&'a str, usize)>

The updates made to the stack environment.

Implementations

impl<'a> MutableStackEnvironment<'a>

pub fn new(bindings: StackEnvironment<'a>) -> Self

Creates a new MutableStackEnvironment with the given backing bindings.

Trait Implementations

impl<'a> MutableStackMap<'a, usize> for MutableStackEnvironment<'a>

fn bind(&mut self, key: &'a str, value: usize)

Inserts a key-value pair into the stack.

impl<'a> StackMap<'a, usize> for MutableStackEnvironment<'a>

fn lookup(&self, key: &str) -> Option<usize>

Looks up a value associated with the given key in the stack.

fn export_key_values<const K: usize>(&self, keys: &'a [&str; K]) -> [usize; K]

Exports the values for the given keys from the local bindings.
