Struct rant::runtime::CallStack

pub struct CallStack { /* fields omitted */ }

Represents a call stack and its associated locals.

Implementations

impl CallStack

pub fn new() -> Self

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

pub fn pop_frame(&mut self) -> Option<StackFrame>

pub fn push_frame(&mut self, frame: StackFrame)

pub fn top_mut(&mut self) -> Option<&mut StackFrame>

pub fn top(&self) -> Option<&StackFrame>

pub fn gen_stack_trace(&self) -> String

pub fn set_var_value(
    &mut self,
    context: &mut Rant,
    id: &str,
    access: AccessPathKind,
    val: RantValue
) -> RuntimeResult<()>

pub fn get_var_value(
    &self,
    context: &Rant,
    id: &str,
    access: AccessPathKind,
    prefer_function: bool
) -> RuntimeResult<RantValue>

pub fn get_var_mut<'a>(
    &'a mut self,
    context: &'a mut Rant,
    id: &str,
    access: AccessPathKind
) -> RuntimeResult<&'a mut RantVar>

pub fn def_var(
    &mut self,
    context: &mut Rant,
    id: &str,
    access: AccessPathKind,
    var: RantVar
) -> RuntimeResult<()>

pub fn def_var_value(
    &mut self,
    context: &mut Rant,
    id: &str,
    access: AccessPathKind,
    val: RantValue
) -> RuntimeResult<()>

pub fn taste_for_first(&self, target_flavor: StackFrameFlavor) -> Option<usize>

Scans ("tastes") the stack from the top looking for the first occurrence of the specified frame flavor. Returns the top-relative index of the first occurrence, or None if no match was found or a stronger flavor was found first.

pub fn taste_for(&self, target_flavor: StackFrameFlavor) -> Option<usize>

Scans ("tastes") the stack from the top looking for the first occurrence of the specified frame flavor. Returns the top-relative index of the first occurrence, or None if no match was found or another flavor was found first.

Trait Implementations

impl Default for CallStack

fn default() -> Self

Returns the "default value" for a type.
