Struct EvalFiber 

pub struct EvalFiber { /* private fields */ }

Implementations

impl EvalFiber

pub fn start_observed( source: &str, env: HashMap<String, Value>, ) -> Result<Self, String>

Creates a live evaluator paused before the first production CPS step.

pub fn start_forms_observed( forms: Vec<Form>, env: HashMap<String, Value>, ) -> Result<Self, String>

Creates a live evaluator paused before evaluating forms without source spans.

pub fn observed_paused(&self) -> bool

Returns true while an observed fiber owns a retained CPS continuation.

pub fn observed_pending_boundaries(&self) -> usize

Returns the number of semantic boundaries retained for host publication.

pub fn step_observed(&mut self) -> EvalFiberState

Executes at most one retained production continuation boundary.

pub fn run_observed(&mut self, boundary_limit: usize) -> EvalFiberState

Runs up to boundary_limit evaluator or queued semantic boundaries.

pub fn resume_observed(&mut self, state: PromiseState) -> EvalFiberState

Applies one real promise settlement without draining later boundaries.

impl EvalFiber

pub fn snapshot_observed_value(&self, source_id: impl Into<String>) -> Value

Returns a bounded JSON-safe document with default observation limits.

pub fn snapshot_observed_value_with_limits( &self, source_id: impl Into<String>, binding_limit: usize, display_chars: usize, ) -> Value

Returns a bounded JSON-safe document without exposing runtime handles.

pub fn step_observed_value(&mut self, source_id: impl Into<String>) -> Value

Executes one production continuation and returns before/after evidence.

pub fn step_observed_value_with_limits( &mut self, source_id: impl Into<String>, binding_limit: usize, display_chars: usize, ) -> Value

Executes one production continuation with caller-selected evidence bounds.

pub fn resume_observed_value( &mut self, state: PromiseState, source_id: impl Into<String>, ) -> Value

Applies one real promise settlement and returns before/after evidence.

pub fn resume_observed_value_with_limits( &mut self, state: PromiseState, source_id: impl Into<String>, binding_limit: usize, display_chars: usize, ) -> Value

Applies one promise settlement with caller-selected evidence bounds.

pub fn pending(&self) -> Option<Promise>

Trait Implementations

impl Drop for EvalFiber

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
