Struct VmEnv 

pub struct VmEnv { /* private fields */ }

VM environment for variable storage.

Implementations

impl VmEnv

pub fn new() -> Self

pub fn push_scope(&mut self)

pub fn pop_scope(&mut self)

pub fn scope_depth(&self) -> usize

pub fn truncate_scopes(&mut self, target_depth: usize)

pub fn get(&self, name: &str) -> Option<VmValue>

pub fn define( &mut self, name: &str, value: VmValue, mutable: bool, ) -> Result<(), VmError>

pub fn all_variables(&self) -> BTreeMap<String, VmValue>

pub fn assign(&mut self, name: &str, value: VmValue) -> Result<(), VmError>

pub fn assign_debug( &mut self, name: &str, value: VmValue, ) -> Result<(), VmError>

Debugger-only variant of assign that rebinds the name even if the existing binding was declared with let. Pipeline authors overwhelmingly use let, so a strict mutability check would make the DAP setVariable request useless for “what-if” iteration — which is the whole point of the feature. Preserves the original mutability flag so the VM’s runtime behavior is unchanged after the debugger overrides.
