Struct Stack 

pub struct Stack {
    pub frames: Vec<StackFrame>,
    pub depth: usize,
}

The frames a runtime error unwound through, innermost first, ending with the top-level form that started the chain when it was recorded.

Fields

frames: Vec<StackFrame>

depth: usize

Activations unwound, recorded or not. Above frames.len() when the recursion was deeper than tatara_lisp_eval::observe::TRACE_FRAMES.

Implementations

impl Stack

pub fn is_empty(&self) -> bool

pub fn of( program: &ResolvedProgram, defs: &Definitions, trace: &Trace, error: Span, top_level: usize, ) -> Self

Read a Trace against the program that ran. error is where the innermost frame raised; top_level the form that was executing.

pub fn json(&self) -> Value

Trait Implementations

impl Clone for Stack

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Stack

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

Formats the value using the given formatter.

impl Default for Stack

fn default() -> Self

Returns the “default value” for a type.

impl Display for Stack

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

at f (file:line:col), one line per frame, a run of identical frames folded into one, at most STACK_LINES lines.

impl Eq for Stack

impl PartialEq for Stack

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
