Struct FrameInfo 

pub struct FrameInfo {
    pub source: String,
    pub line: u32,
    pub line_defined: u32,
}

One activation record projected from a live Vm.frames. Used by frames_for_profile to feed the luna-profile sampler. Owned strings so the caller can keep samples across dispatch ticks without holding a &Vm borrow.

Fields

source: String

Lua source / chunk name (Proto.source, decoded as UTF-8 lossy). Mirrors what debug.getinfo(level, "S").source reports — minus the leading @/= PUC-style chunk prefix is preserved verbatim.

line: u32

Line number of the currently-dispatched instruction, derived from Proto.lines[pc - 1]. 0 when the frame’s PC hasn’t advanced past the entry yet (a freshly pushed frame mid-call setup) — extremely rare from a Count hook, but tolerated.

line_defined: u32

Proto.line_defined — the line the function’s function keyword was on. Useful to differentiate two closures with the same source but different definition lines.

Trait Implementations

impl Clone for FrameInfo

fn clone(&self) -> FrameInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FrameInfo

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

Formats the value using the given formatter.

impl Eq for FrameInfo

impl Hash for FrameInfo

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FrameInfo

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
